Biotite is a common phyllosilicate mineral belonging to the mica group. It is found in a wide range of geological settings, including igneous, metamorphic, and sedimentary rocks. Biotite is characterized by its dark color, typically black or dark brown, and its perfect cleavage, which allows it to be easily split into thin, flexible sheets.
Physical Properties
Biotite has a monoclinic crystal structure and a hardness of 2.5 to 3 on the Mohs scale. It has a specific gravity ranging from 2.7 to 3.3 and a vitreous to pearly luster. Biotite crystals are often tabular or prismatic in shape and can exhibit a wide range of colors, including black, brown, green, and red, depending on the mineral impurities present.
Formation and Occurrence
Biotite commonly forms in igneous rocks such as granite and diorite as a primary mineral during the crystallization of magma. It can also be found in metamorphic rocks like schist and gneiss, where it forms due to the recrystallization of pre-existing minerals under high temperature and pressure conditions. Additionally, biotite is present in some sedimentary rocks, where it may have been deposited as detrital grains or formed through diagenesis.
Uses
Biotite has several industrial applications, including its use as a source of potassium in fertilizers and as a constituent of drilling muds in the oil and gas industry. In addition, biotite is used in the manufacture of building materials such as concrete and asphalt. Some varieties of biotite are also prized by collectors for their attractive crystal forms and colors.
In summary, biotite is a versatile mineral with wide-ranging geological occurrences and industrial uses. Its distinctive physical properties make it a valuable mineral for both scientific study and practical applications in various industries.
