Asbestos Details - Knight Armour, Environmental and Engineering Services, Denver, Colorado.
Asbestos is a naturally occurring mineral.
It differs from other minerals in its crystal development. The crystal formation of asbestos is in the form of long thin fibers. The division between the two types of asbestos is based upon the crystalline structure. Serpentines have a sheet or layered structure where amphiboles have a chain-like structure. As the only member of the serpentine group, Chrysotile is the most common type of asbestos found in buildings.
