Biotite is a common ferromagnesian mica occurring in igneous and metamorphic rocks. Its iron–magnesium composition varies with pressure–temperature conditions, making it an important index mineral for assessing metamorphic grade and in deciphering tectono-thermal evolution of the continental crust. #GeologicalSurveyofIndia #MineraloftheWeek #Biotite #Mica #GeoPedia #Geologykefunde | Geological Survey of India
