It is a common potassium aluminum silicate mineral with the chemical formula KAlSi3O8. Belonging to the framework silicate mineral, it is a member of the feldspar family. It usually appears as pink, yellow, green, or white, but the most typical color is light yellow or orange red, which comes from trace amounts of iron and manganese impurities. The crystal structure is monoclinic, with various crystal shapes, commonly including short columnar or plate-like structures. It has two sets of complete cleavage, which allows it to easily crack along a specific direction. Widely distributed in nature, commonly found in granite, syenite, gneiss, and some metamorphic rocks. It is also an important mineral formed during many metamorphic processes.
