What is amphibole asbestos?
Amphibole asbestos is a subgroup of asbestos that can be distinguished by its straight, needle-like fiber-formation. Five of the six types of asbestos are amphiboles (tremolite, actinolite, anthophyllite, crocidolite and amosite). Chrysotile is the only type of asbestos that does not fall into the category of amphibole asbestos. Chrysotile has a curled fiber-formation, making it a type of serpentine asbestos.
