Asbestos is the common name given to a group of naturally occurring mineral silicates that can be separated into flexible fibres. This is a very flexible fibre which is often woven into fabrics and textiles. These often have a natural content of asbestos minerals from the amphibole family like actinolite, tremolite, anthophyllite, amosite (grunerite). See above Actinolite sample for an extended discussion of asbestos, mesothelioma, lawyers, and litigation. Name is derived from an acronym of an original mining locality (AMOSA Mine, Asbestos Mines Of South Africa).
