  • Andalusite


    Andalusite is an aluminosilicate mineral, which is the raw material for making refractory materials and porcelain in spark plugs. It is a typical mineral of low-grade thermal metamorphism, and is commonly found in mudstones in contact with metamorphic zones. It is mainly formed under the conditions of high geothermal gradient and low pressure to temperature ratio.
