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.
Asbestos refers to six unique substances that belong to the serpentine and amphibole mineral families: chrysotile, amosite, crocidolite, tremolite, anthophyllite, and actinolite. These terms do not refer to mineral descriptions but to a broad term that refers to unique fibers.
