Hydrothermal Solution activity in Precambrian Granitoides in Dasarigudem Village Nalgonda District Telangana India

Interaction of hydrothermal circulation in fractured rocks is a common feature in crystalline sequence. In the study area the granitic rock adjacent to fractures in Dasarigudem village northern Nalgonda, has been studied with emphasis on this mineral reactions and associated element mobility occurred during the alteration. The reaction occurred with hydrothermal solutions are complete saussuritization of plagioclase accompanied by chloritization of biotite. Magnetite had been replaced by hematite whereas K- feldspar altered into sericitization and Quartz also effected by hydrothermal solutions. Under the microscope, the quartz grain edges are marked as saw. This is due to fluorine (HF) react with Quartz and amalgamated into them from their edges.
