Microscopic photograph of asbestos.

The amphiboles in metamorphic

rocks can form very long and thin

crystals

Most commercial asbestos comes from chrysotile, a fibrous variety of the mineral serpentine (amphibole)

Asbestos was used in older buildings as

insulation, roofing material, and other

heat or fire proof applications

Asbestos removal is

happening all over the world

Amphiboles are an important component of many decorative building stones, where their colors contribute to the stones’

decorative pattern

Jade is made of amphibole or pyroxene,

and prized in Chinese,

and jadeite (a pyroxene)

are nearly
