Trang 1der the jurisdiction of the coastal state for specific
purposes The convention, the work of more than
fourteen years of negotiation, is a comprehensive
le-gal document that created an ordered system for the
use of ocean space and for the protection of the
natu-ral resources of the oceans
According to customary use of the seas, the area
be-yond the territorial waters of a state had been
consid-ered “high seas,” open to use by all and under no
na-tion’s jurisdiction The territorial waters had been
generally accepted as extending 4.8 kilometers from
the coast into the sea Then, in the Truman
Proclama-tion of September 28, 1945, the United States claimed
the right to extend its jurisdiction over “conservation
zones” in the high seas contiguous to the U.S coast
Other countries followed, establishing their own zones
and extending their economic jurisdiction into the
high seas Many maritime nations feared that the
tradi-tion of open seas and free navigatradi-tion would end Thus
in 1967 the United Nations General Assembly
estab-lished an ad hoc committee to begin studying peaceful
uses of the seas in preparation for convening the Third
United Nations Convention on the Law of the Sea
Provisions
A dispute over coastal rights and claims versus the
freedom of all to use the seas erupted at the first
ses-sion of the conference in Caracas, Venezuela The
cre-ation of an economic zone of protection for a coastal
state’s offshore resources was one of the first
agree-ments negotiated at the conference The EEZ part of
the convention was put together as a smaller part
within the overall package, which was a carefully
nego-tiated compromise document The EEZ extends up to
200 nautical miles from a baseline drawn along the
low-water line of a coast
Impact on Resource Use
Within that zone the coastal state acquires sovereign
economic rights over living and nonliving resources
for the purpose of exploitation, conservation, and
re-source management, including the right to establish
the allowable catch of living resources All other states
retain their rights under the freedom of the seas
con-cept and retain access to the EEZ for the purpose of
exploiting those resources that the coastal state does
not use
Should disagreements arise with respect to the EEZ
area, the convention calls for them to be settled on the
basis of equity, and in the interests of all parties and of
the international community as a whole An interna-tional tribunal is provided for the settlement of dis-putes that may arise regarding the use of ocean space and EEZ resources

Exxon Valdez oil spill
Category: Historical events and movements Date: March 24, 1989
The Exxon Valdez oil spill, in which 42 million liters
of crude oil spilled into Prince William Sound off the Alaskan coast, demonstrated the destructive power of oil It contaminated approximately 2,100 kilometers of pristine shoreline, killing and endangering wildlife Twenty years later, oil was still surfacing in some areas and two species had not recovered, while others still struggled to recover.
Background
At 12:04 a.m on March 24, 1989, the oil tanker Exxon Valdez plowed into Bligh Reef about 161 kilometers
off the coast of Alaska The 301-meter tanker had di-verted course out of the narrow shipping lane to avoid icebergs but hit the reef before turning back on course Of the more than 200 million liters of crude oil it carried, 42 million flowed into Prince William Sound The close proximity to the shore, stormy seas, and high winds all contributed to the contamination
of 322 kilometers of shoreline The slick stretched 740 kilometers, reaching the village of Chignik on the Alaskan Peninsula
Response efforts were delayed and inadequate Lit-tle of the oil was scooped from the waters, because a response barge was out of service Not enough skim-mers and booms designed to contain a spill were avail-able Dispersants used to break up the oil for easier cleanup were not effective, because of weather condi-tions Though the seas calmed in the following days, the oil slick spread, lightly coating another 684 kilome-ters of shoreline In all, an estimated 250,000 seabirds, 2,800 sea otters, 250 bald eagles, 22 killer whales, 300 harbor seals, and billions of fish were killed The
Trang 2lapse of the Pacific herring fishery, which devastated
local economies, is blamed on this event
Impact on Resource Use
The Exxon Valdez Oil Spill Trustee Council was
estab-lished to oversee restoration efforts in the sound
Cleanup efforts took six months at a cost of about
$2.1 billion to Exxon Corporation Though no longer
listed as one of the top fifty oil spills in terms of the
amount of oil expelled, this event remains one of the
most devastating oil spills in terms of environmental
impact
This incident established changes in response and
recovery Practice response drills are held in Prince
William Sound twice yearly Seven barges are available
in case of a spill, and 64 kilometers of boom and a
stockpile of dispersants are on hand The U.S Coast
Guard now monitors vessels passing through the
nar-row shipping lane in the sound, and two vessels
ac-company fully laden tankers to offer assistance in
emergencies In addition, Congress enacted a law
re-quiring tankers traveling through Prince William
Sound to be double-hulled The oil industry now uses double- and triple-hulled tankers
Despite the devastation and far-reaching effect of the oil spill, the environment was expected to recover within several years Areas of shoreline that were lightly coated did recover In 1994, five years after the
accident, the Exxon Valdez Oil Spill Trustee Council
compiled an official list of resources and services af-fected by the spill Twenty years after the spill, areas most heavily contaminated still showed oil surfacing from beneath rocks and pebbles Only ten, or one-third, of the resources and services listed are consid-ered “recovconsid-ered.” Recovery of many of these resources and services is dependent on recovery of others Oil spills are no longer considered acute, short-term envi-ronmental threats

Farmland
Category: Ecological resources
Agricultural soil able to produce sufficient food and
fi-ber to feed and clothe the growing human population is
one of the world’s most important natural resources.
Background Land suitable for agriculture is not evenly distributed throughout the world; it tends to be concentrated in limited areas In order to be considered arable, land must be located in an area with the right combination
of environmental conditions First, the land must be located at the proper elevation and slope Because the soil supplies all the mineral nutrients required for plant growth, it must also have the appropriate fertil-ity, texture, and pH level Approximately 64 percent
of the world’s land has the proper topography, and about 46 percent has satisfactory soil fertility Plants require large amounts of water for pho-tosynthesis and access to soil nutrients; therefore, farmland must have an adequate supply of mois-ture, either as rainfall or as irrigation water About
46 percent of the world’s land has adequate and reliable rainfall Because plant growth is dramati-cally affected by temperature, farmland must be located in areas with growing seasons sufficiently long to sustain the crop from planting to harvest Approximately 83 percent of the world’s land has favorable temperatures Plants also require suffi-cient sunlight and atmospheric carbon dioxide levels to support the photosynthetic process nec-essary for growth and development Virtually all the world’s land has adequate sunlight and suffi-cient carbon dioxide to support plant growth Crop production requires the right combination
of all these factors, but only about 7 percent of the world’s land has the proper combination of these factors to make the production of crops feasible without additional technological advances
Farmland in the United States With its temperate climate, the United States de-votes considerably more of its land area to agricul-ture than do many other countries About 45 per-cent of the land in the United States is utilized for various forms of agriculture; however, not all this land is devoted to crop production Only about 20 percent of the land is actual cropland Approxi-mately 4 percent is devoted to woodlands, and the other 21 percent is used for other purposes, such
Farmland, like this field in Wyoming, composes a significant portion of

Trang 4as pastures and grasslands Of the farmland devoted
to crop production, only 14 percent is used at any given
time to produce harvestable crops Approximately 21
percent of this harvested cropland is used to produce
food grains for human consumption Another 31
per-cent is used to grow feed grains for feeding livestock,
and the remaining 48 percent of harvested cropland
is devoted to the production of soybeans, oil, seed,
fiber, and miscellaneous crops
Seven major agricultural regions exist in the
United States The dairy region is located in the
North Atlantic states and extends westward past the
Great Lakes and along the Pacific coast The wheat
belt is centered in the central and northern Great
Plains and in the Columbia basin of the Northwest
The general and self-sufficient regions primarily
made up of small, family-owned farms are found
mostly in the eastern highlands region, which
in-cludes the Appalachian Mountains—a few hundred
kilometers inland from the Atlantic Coast—and the
Ozark-Ouachita mountains west of the Mississippi
River The corn and livestock belt is found
through-out the midwestern states The range-livestock region
of the western United States stretches in a band from
800 to 1,600 kilometers wide and extends from the
Ca-nadian border to Mexico The western specialty-crops
area is primarily composed of irrigated land in
seven-teen western states and produces the vast majority of
the nation’s vegetable crops The cotton belt, located
in the southern states (most notably Georgia,
Ala-bama, and Mississippi), contains more counties with
more farmers than any other region While this area
has been known historically for its cotton production,
many other goods—including tobacco, peanuts, truck
crops, livestock, and poultry—are also produced in
the South In addition to these major regions, smaller
farming areas are located throughout the country
To-bacco is produced in localities throughout Kentucky,
Virginia, Tennessee, and North and South Carolina
Apples and other fruits are grown in a variety of places,
including the Middle Atlantic seaboard, around the
Great Lakes, and in the Pacific Northwest Potatoes
are produced in Maine, Minnesota, Idaho, North
Da-kota, and California Citrus is grown in southern
Texas, Florida, and California Sugarcane is grown in
southern Louisiana and Florida
Canada
In addition to the rich farmland of the United States,
good farmland exists in neighboring Canada
Al-though the arable land percentage in Canada is only 4.57, that amount is sufficient to produce large yields
of wheat, barley, oilseeds (including flax and sun-flower), tobacco, fruits, and vegetables Canada also is
a large producer of dairy products from its many dairy farms and seafood products from both Atlantic and Pacific fisheries
Eurasia
On the Eurasian continent, important farmland re-gions are found in the Ukraine, Russia, China, and In-dia Ukraine has one of the largest areas of arable land
in the world, with 53.8 percent of its land total consid-ered suitable for farming However, only 1.5 percent
of the country’s production is in permanent crops, a possible indication that more farming might occur in the country if economic conditions are more stable Ukraine is a large producer of sugar beets, sunflower seeds, vegetables, beef, and milk
Neighboring Russia, which has long been consid-ered one of the world’s “breadbaskets,” grows the same crops as Ukraine, but on only 7.17 percent of its area Some of Russia’s farmland has been lost to devel-opment and desertification as well as rendered unsafe
by excess and improper uses of agricultural pesti-cides
China owes more than 43 percent of its gross do-mestic product to agricultural production and is a leading producer of rice, wheat, potatoes, corn, pea-nuts, and tea Millet, barley, apples, cotton, and oil-seeds are produced in China in smaller amounts but are nevertheless important to the country’s economy China has only 1.27 percent of its land in permanent crops, and 14.86 percent of the country’s land is con-sidered arable However, China is facing a very serious problem in that at least one-fifth of its agricultural land has been lost since the 1950’s, primarily because
of soil erosion and economic development China has therefore passed laws that exact severe penalties for the conversion of farmland to any type of develop-ment in an attempt to conserve remaining agricul-tural lands
India, like Ukraine, has one of the highest propor-tions of arable land in the world, with 48.83 percent of usable farmland in the country Rice, wheat, oilseeds, cotton, jute, tea, sugarcane, potatoes, and livestock are produced on 2.8 percent of land devoted to per-manent agricultural use A rapidly growing popula-tion and severe water pollupopula-tion are two problems detrimental to farming in India
Trang 5South America
Brazil is the third largest agricultural producer in the
world behind the United States and the European
Union On approximately 6.93 percent of its total
land area and with less than 1 percent devoted to
per-manent crops, Brazil is number one in the world in
ex-ports of coffee, frozen orange juice, and sugar It is the
world’s second largest producer of soybeans, tobacco,
beef, and poultry Brazil’s problems with habitat
frag-mentation, water pollution, and non-farm
develop-ment plague this important South American nation
in terms of its ability to continue to be a major
agricul-tural producer
Argentina is another important producer of crops
in South America It produces soybeans and cereal
grains, including corn and wheat The country has
been a major producer of beef for many years Cereal
crops and cattle are produced on about 10 percent of
the country’s land area
Farmland Degradation
All of the developed and developing countries
around the world are encountering many of the same
problems involving the loss or degradation of
farm-land Within developed countries the most serious
problems are outright destruction of farmland by
de-velopment Urban, suburban, and residential
devel-opments destroy thousands of hectares of farmland
daily, and unless governments act to preserve
farm-land within their countries, it is unlikely that
agricul-tural production will be able to keep pace with the
ex-ploding world population
In the United States, both the amount of land
de-voted to farming and the number of farmers began
decreasing after 1965 The amount of good farmland
worldwide has also decreased Most of this decrease is
attributed to a combination of urbanization and poor
agricultural methods that have led to loss of topsoil
through water and wind erosion Historically, large
tracts of farmland have been located near major
met-ropolitan areas In recent times, these urban centers
have grown outward into large suburban areas, and
this sprawl has consumed vast areas of farmland
Ero-sion destroys thousands of hectares of farmland every
year, and desertification—the conversion of
produc-tive rangeland, rain-fed cropland, or irrigated
crop-land into desertlike crop-land with a resulting drop in
agri-cultural productivity—has reduced productivity on
more than 80 million hectares since the 1960’s In
many cases, the desertified land is no longer useful as
farmland Because most of the world’s available farm-land is now in production, steps must be taken to pre-serve this valuable resource, or the world could suffer mass food shortages in the future
Degradation of world farmland is occurring at a rapid pace Desertification of formerly fertile areas is taking place on every continent that has farmland Water pollution, from both industrialized areas and agricultural runoff, is a serious concern in most coun-tries In addition to water pollution, the loss of water available for irrigation is affecting many farming ar-eas Global climate change is altering rainfall patterns throughout the world, with some areas receiving too much rainfall and others too little Throughout many parts of the United States, for instance, the water table has fallen drastically, as too much water has been with-drawn for both urban and agricultural uses Govern-ments, whether national or local, must continue to search for reasonable ways to balance water use among competing interests in order for agricultural produc-tion to continue

Federal Energy Regulatory
Commission
Category: Organizations, agencies, and programs
Date: Established 1978
The Federal Energy Regulatory Commission regulates
a number of aspects of energy, including hydroelectric
power, oil and natural gas, and wholesale sales of
elec-tricity, in which interstate commerce is involved.
Background
The Federal Energy Regulatory Commission (FERC)
was established in 1978 At that time, as part of the
new cabinet-level Department of Energy (established
in 1977), the responsibilities of several different agen-cies dealing with energy issues were combined and given to one independent regulatory commission The Federal Power Commission (FPC), the most di-rect predecessor to the FERC, had been responsible for overseeing interstate issues involving the genera-tion and transmission of electricity and the develop-ment and regulation of hydroelectric facilities The FERC continues to regulate electricity, but it also over-sees a variety of other energy resources if interstate commerce is involved
The FERC’s regulation of hydroelectric develop-ment is historically the oldest component of the agency’s responsibilities The Federal Water Power Act of 1920 centralized authority for federal oversight
of water power development in one agency, the FPC The agency as originally established was both small and weak, consisting of only one permanent em-ployee, an executive secretary Support staff were borrowed from other agencies, and engineering re-views of proposed projects were performed by con-sulting engineers Still, the FPC managed to establish guidelines that prevented wildcat speculations and conserved federal wilderness areas
Congress reorganized and gradually strengthened the FPC several times in the following decades In
1935, the Federal Power Act added regulation of the interstate transmission and wholesale sale of electric-ity to the FPC’s responsibilities, while the Public Util-ity Regulatory Policies Act (PURPA), passed during the energy crisis of the 1970’s, added provisions to encourage cogeneration and alternative energy re-source development More recently, the Energy Pol-icy Act (2005) clarified regulation of natural gas and oil transported across state lines
Impact on Resource Use The FERC’s responsibilities include regulating the transmission of natural gas and oil by pipeline in in-terstate commerce and the transmission and sale of electricity in interstate commerce FERC licenses and inspects private, municipal, and state hydroelectric projects and oversees related environmental matters The FERC’s mission in overseeing wholesale sales
of electricity is to ensure that utilities charge reason-able rates and that federal public utility regulations regarding officers and directorships of utility compa-nies are obeyed Rates set by federal power generating agencies, such as the Bonneville Power Administra-tion, are also reviewed by the FERC The retail rates
Trang 7paid by consumers are regulated within the individual
states by public utilities commissions
The FERC consists of five members appointed by
the president Members serve for five years When the
commission was established, terms of office were
stag-gered so that only one member’s term would expire
each year The president of the United States
desig-nates the chairperson for the FERC, and, in the event
that a vacancy occurs on the commission, anyone
ap-pointed to fill that vacancy serves only the remainder
of that particular term Although no specific
qualifi-cations were set for commission members, the
legisla-tive mandate does require that the president appoint
to the commission persons who are familiar with
en-ergy issues and procedures
In overseeing natural gas and oil, the FERC
regu-lates the construction of pipelines and other methods
used in interstate transportation of these resources as
well as the facilities at wellheads and at distribution
points At one time, the FERC was required to
estab-lish ceiling prices for natural gas, but the Natural Gas
Wellhead Deregulation Act of 1993 eliminated that
practice

Federalism and resource
management
Categories: Environment, conservation, and
resource management; social, economic, and
political issues
Natural resources management plays a key role in
con-serving and enhancing those goods and services
pro-vided by nature Management practices in the United States are guided by the federalism model, providing
an integrated mode of management structured around the needs and capabilities of local, state, and national efforts.
Background Federalism refers to the institutional framework that divides decision-making power between the national government and individual states In this framework, both national governments and states develop laws and public policies
Before the United States ratified its constitution, the states acted autonomously In the immediate af-termath of the signing of the Constitution in 1787, thenational government dealt primarily with national issues, such as defense Over time, changes in this bal-ance of power occurred directly in the form of amend-ments to the Constitution and legislative actions As an example of an explicit allocation of decision-making power, the Tenth Amendment to the U.S Constitu-tion declares, “powers not delegated to the United States are reserved to the States .” The U.S na-tional government has increased its power over time, especially in response to large national events, such as the Civil War and the Great Depression
As a subset of federalism, environmental federal-ism refers to a dynamic balance of power between the states and the federal government, which is deter-mined by the nature of the role played in establishing environmental protection and managing natural re-sources Natural resources include both renewable and nonrenewable resources: soil, minerals, forests, water, fisheries, and energy In response to natural re-source scarcity and the degradation of environmental quality, Congress has designed environmental pro-grams that allow for implementation of policies to manage and protect these resources on the federal, state, and local levels
History of Natural Resource Policy and Management
William Lowry describes the evolution of natural re-source policies as divided into the following three eras: an era from colonial times to the end of the nine-teenth century in which government did not get involved in resource extraction and most viewed re-sources as abundant; an ongoing era in which govern-ment determines natural resource policies; and a new era in which policies are determined by synthesizing
Trang 8the preferences and perspectives of different, often
competing, stakeholders
Before the shift to government involvement in the
allocation of natural resources, a majority of the
pub-lic perceived natural resources to be abundant As the
public began to utilize the expansive resources of the
United States, it became evident that a lack of natural
resource and public land management was leading to
the exploitation of numerous types of natural
re-sources, including wildlife, rangelands, and forests In
response to this exploitation, the federal government
increased its role in the management of these
re-sources
For much of the twentieth century and into the
twenty-first century, natural resource policy and
man-agement focused on the manman-agement of individual
resources rather than taking a more holistic view of
public resources As a result of this segmented
ap-proach, management responsibilities are divided
among an array of state and federal agencies The
division of management between the federal
govern-ment and state and local governgovern-ments is often
de-scribed as a vertical division Within the U.S
govern-ment, the largest land and resource management
agencies are the Bureau of Land Management, the
U.S Fish and Wildlife Service, the National Park
Ser-vice, and the U.S Forest Service These four agencies
manage roughly 250 million hectares of land Other
federal agencies also play key roles in managing
natu-ral resources, including the U.S Army Corps of
Engi-neers, the Minerals Management Service, and the
Na-tional Oceanic and Atmospheric Administration State
and local governments also play an important role in
land management, with roughly 23 million hectares
under management These estimates do not include
the 11.7 million square nautical kilometers of ocean
under U.S jurisdiction
Public Policy and Natural Resources
Management
Public policy refers to government action or inaction
in response to some type of social problem
Manage-ment either involves day-to-day efforts on the ground
(or water) or the efforts to control agencies that
over-see those day-to-day efforts Management represents
a distinct form of policy implementation It can be
conceptually divided into two separate categories:
strategic management and operational management
Strategic management refers to those efforts that
de-termine the organizational/institutional structure;
op-erational management refers to on-the-ground ac-tions of the agencies
Natural resource management is not a science Ideally, natural resource management will be guided
by both natural and social sciences but influenced by a host of other factors, including the values and the sub-jective processes of managers and resource stake-holders Managers have the difficult task of bridging gaps between management, policy, and science
General Issues in Environmental Federalism One topic garnering continued discussion is the proper way to evaluate the balance of power between the federal government and the state governments This requires determining how the vertical divisions
of decision making influence the management of nat-ural resources Which level of government has the best claim on the management of the resource and which level of government can manage the resource most efficiently are two factors that must be deter-mined
Several benefits of lower-level, or local (state, city, and county), government jurisdiction exist Local governments promote citizen involvement in self-governance, are often more responsive to the needs and preferences of local citizens, and tend to be more cost-effective Skeptics of local government effective-ness point out that they often do not have the neces-sary resources to perform well In addition, detractors also assert that some environmental issues are larger than local jurisdictional boundaries For example, air pollution is not likely to stay in certain geographical boundaries, because of natural shifts in global wind patterns
One of the ongoing debates over environmental federalism concerns the correct balance of power Re-searchers have found that different levels of govern-ment produce different policies One major cause can be attributed to the perceived consequence of localized versus national decision making In some instances, lower levels of government are more likely
to encourage developmental policies, like economic growth, over redistributive policies This can be traced
to fears that residents may move to nearby locations with more pro-growth policies On a national level, redistributive policies, such as those protecting envi-ronmental quality and natural resource abundance, can be more effective because individuals and firms are less likely to move beyond national boundaries Theorists have described this localized tendency to
Trang 9favor development, as it affects environmental quality
and natural resources, as a “race to the bottom.” This
refers to situations in which state and local
govern-ments favor development over environmental quality,
allowing for lower environmental standards This
per-ception has been disputed in academic literature In
some cases, states have exceeded existing federal
stan-dards In practice, states and local governments have
actually developed a whole host of innovative policies
On the localized level, state and local governments
benefit from having the ability to tailor policies to
meet the specific needs of a given area Local levels of
government also tend to be more cost-effective than
the federal government
The federal government has played a key role in
the development of laws protecting the environment
and natural resources However, the federal
govern-ment does not always have the ability or the
knowl-edge to tailor policies to meet regional or localized
needs The federal government is well suited to
ad-dress issues that are large in scale or that cross more
lo-calized jurisdictional boundaries
Collaborative Outputs of Natural Resource
Policy
In application, there are numerous cases in which
states and the federal government collaborate in the
management of natural resources One example of
this occurs via the management of marine fisheries
in the United States Marine fisheries represent a
unique natural resource requiring both state and
fed-eral attention, because some fish exist locally, but
other fish have large migration patterns crossing
nu-merous jurisdictional boundaries Marine fisheries
are a type of common-pool resource which, without
oversight, are often depleted In most cases, states
control waters out to 5.6 nautical kilometers (the
ex-ceptions are Texas, Florida’s Gulf coast, and Puerto
Rico, which control waters out to 16.7 nautical
kilo-meters), and the federal government controls waters
out to 370 nautical kilometers Of course,
environ-mental systems do not adhere to these types of
juris-dictional boundaries, thus necessitating collaborative
efforts
In response to these challenges, Congress passed
the Magnuson-Stevens Fishery Conservation and
Management Act of 1976 (amended in 1996 and
reauthorized in 2006) to outline principal goals in
conservation and management of fish, while
simulta-neously promoting safety and efficiency
The Magnuson-Stevens Act relies on collaboration between state and federal governments The National Marine Fisheries Service (NMFS) acts as the lead fed-eral agency for the management of fisheries in fedfed-eral waters The act also designated regional management councils to advise the NMFS in this management effort These management councils are composed
of representatives from state fisheries management agencies, mandatory appointees from coastal states, at-large appointees from states in the region, and the regional directors of NMFS The fisheries manage-ment councils have the vital responsibilities of creat-ing Fisheries Management Plans (FMPs), which desig-nate fish in need of management, analyze factors (both natural and social) influencing the fishery, and prepare the FMP to balance environmental, social, and economic goals In the case of fisheries, states have the important role of managing fish in their jurisdic-tion as well as participating in regional management responsibilities, such as educating commercial and rec-reational fishermen and promoting the safe, legal fish-ing practices outlined in the Magnuson-Stevens Act
Context Federalism is the operating system used by the United States to manage its natural resources Considering the goals for resource management, such as conserva-tion and protecconserva-tion, good working relaconserva-tionships be-tween federal and local agencies are necessary to en-sure the most efficient and most effective supervision Goals at the local and national levels are intertwined, creating opportunities to work together to maximize benefits to and from the natural resources available

Feldspars
Category: Mineral and other nonliving resources
Feldspars are the most common minerals on the Earth’s
surface They are a major component in most igneous
rocks, available in inexhaustible supply.
Where Found
The largest concentration of feldspars occurs in
igne-ous pegmatites, where zones of pure orthoclase that
are greater than 30 meters thick are common China,
France, Italy, Mexico, Spain, Thailand, Turkey, and
the United States together produce roughly 75
per-cent of the world’s feldspar; most U.S feldspar is
ob-tained in North Carolina
Primary Uses
Feldspar is ground for use in industries as scouring
soaps, ceramics, glassmaking material, and pottery A
plagioclase feldspar called labradorite and an alkali
feldspar called moonstone show such a strong “play of
colors” that they are used as semiprecious gemstones
Technical Definition
The common feldspars are expressed in terms of
mixtures of three end-member compositions;
ortho-clase, KAlSi3O8; albite, NaAlSi3O8; and anorthite,
CaAl2Si2O8 A feldspar that is a mixture of orthoclase
and albite is called an alkali feldspar, and any member
that is a mixture of albite and anorthite is known as a
plagioclase feldspar Orthoclase feldspar will change its crystal shape when exposed to prolonged periods
of higher or lower temperatures; the high-tempera-ture form is named sanidine, and the low-tempera-ture form is microcline Good cleavage in two direc-tions at an angle of 90° is characteristic of all feldspars The hardness of feldspars ranges from 6 to 6.5, and the specific gravity, excluding barium feldspars, is 2.55 to 2.76
Description, Distribution, and Forms Feldspar is the name given to members of a group of closely related anhydrous aluminum silicate minerals that vary in the chemical percentages of potassium, sodium, calcium, or, more rarely, barium in their for-mulas
The internal atomic arrangements of the elements
in all feldspars is similar except for aluminum Its dis-tribution in the structure depends on the tempera-ture of formation of the feldspar High-temperatempera-ture sanidine shows a random distribution of aluminum within the atomic sites where aluminum and silicon occur, whereas low-temperature microcline shows a completely ordered arrangement of the aluminum ions
The mining and processing of feldspar do not cause major disturbances to the environment Feld-spar is highly concentrated in the mined rock, so there is relatively little dump material and only a small pit needing reclamation There are relatively few toxic chemicals utilized in the mining and processing of the rock, thereby restricting the possibilities for polluting the environment The primary crushing of feldspar is done outside, so prolonged respiratory intake of silica dust can be avoided Indoor dry milling requires the use of sufficient artificial ventilation to guard against dust inhalation
History Feldspars appear to have been mined by American In-dians before the discovery of the Americas by Europe-ans Feldspar or feldspathic sand is evident in prehis-toric pottery It is thought that feldspar obtained from American Indians was shipped from what is now the state of North Carolina to Europe in 1744 Commer-cial feldspar production started in Connecticut in
1825, with the mining of alkali feldspar from an igne-ous pegmatite The feldspar was hand-sorted, packed into barrels, and shipped to the United Kingdom In
1850, a mill was constructed in Middletown,
