Brief Description: Chrysotile: from the Greek terms chrysos (gold) and tillo (moult) because of its colour and its fibrous form. It constitutes a silicon mineral of magnesium, which is a fibrous variety of serpentine and one of the most important asbestos minerals. Its chemical formula is Mg6Si4O10(OH)8 and it belongs to the category of Phyllosilicates. It has a waxy lustre in solid varieties and silky in fibrous. It is transparent to semitransparent, infusible, with hardness ranging 3 - 5 and specific gravity from 2.5 to 2.6. It has a greasy or sebaceous texture. It mainly occurs in transmuted crystals in form of veins inside a fundamental mass of lizardite. The fibrous version (chysotile) is widely used as asbestos for thermal and electrical insulations. Furthermore, the solid variety with light to dark colour and mixed with calcite material, known as ?serpentine marble? is used for ornamental and structural purposes. There are two serpentine varieties, the leaf-like one called antigorite and the fibrous one called chrysotile (asbestos).
