Asbestos is the name applied to a group of six naturally occurring fibrous minerals (chrysotile, amosite, crocidolite, plus the fibrous varieties of actinolite, tremolite, and anthophyllite). Non asbestos (non fibrous) forms of tremolite, actinolite, and anthophyllite also are found in nature. https://dyrectory.com/asbestos-audits-queensland-100627.html
