There are two main categories of asbestos: amphibole asbestos and serpentine asbestos. The serpentine asbestos group contains one type of asbestos, chrysotile. The amphibole asbestos group consists of several types of asbestos: amosite, crocidolite, anthophyllite, tremolite, and actinolite.
Serpentine asbestos includes the mineral chrysotile, which has long, curly fibers that can be woven. Chrysotile asbestos is the form that has been used most widely in commercial applications. Amphibole asbestos includes the minerals actinolite, tremolite, anthophyllite, crocidolite, and amosite.
