Clastic rock geochemistry of the Sirohi Basin, Aravalli Craton, NW India: Implications for paleoweathering, provenance and geodynamics
Sirohi Basin Nails of Trans-Aravalli Region, Rajasthan preserves a thick clastic sequence composed of phyllite and metasandstone.Based on their petrochemical properties, metasandstone is classified as K-feldspar rich wacke (Wacke I) and plagioclase rich wacke (Wacke II).Wacke I is characterised by higher K2O, Fe2O3 and lower CaO, Na2O, and Na2O/K2O
