- How Is Biotite Mined And Processed
Chloritization of biotite in a hydrothermal environment was studied in two granitic rocks of the Massif Central (France). Four types of transformation were observed: (1) Mg-chlorite growth upon (001) biotite planes in contact with quartz; (2) biotite pseudomorphosed by a corrensite—residual biotite assemblage; (3) …
