Geochemistry and Petrogenesis of Pyrophyllite Deposit of Madrangjodi, Keonjhar District, Orissa
Subscribe/Renew Journal
Pyrophyllite deposit at Madrangjodi is a large lensoidal massif overlain unconformably by Dhanjori quartzite and underlain by the parent Singhbhum granite (Phase - II). Pyrophyllite and quartz are the major minerals with minor to trace amounts of muscovite, chloritoid opaques and tourmaline. It is broadly divisible into lamellar, granular and schistose varieties. SiO2 (66.90-74.36 %) and Al2O3 (20.80-27.54 %) are the major oxides. The major elements data indicate its derivation from Singhbhum granite with depletion of SiO2 and increment of Al2O3. Trace and REE data are discussed to corroborate its genesis.
