Provenance, Weathering and Tectonic Setting of Talchir Formation in Parts of Son Valley Sub Basin Chhattisgarh, India During Late Paleozoic Era: Petrological and Geochemical Evidences

Khansa Zaidi, Sarwar Rais

Abstract :

The Talchir Formation (Permo-carboniferous) is the lowermost unit of Gondwana Supergroup which rests unconformably over the Precamian basement of Indian peninsula. Modal analysis and geochemistry of Talchir sandstones and shales of Chirimiri area, Son valley sub basin, Chhattisgarh, is carried out to know nature of provenance and its composition, weathering condition and tectonic setting of both source area and depositional basin. These characters are determined with the help of QtFL parameter, and bivariate plot between TiO2 vs Zr, geochemical proxies [A/ACNK)*100] and ratio of major oxide K2O/Na2O vs SiO2 have been utilised to achieve this aim. The petrochemical attributes of the clastic rocks of Talchir Formation suggest that these sediments have been derived from continental block having rocks of mixed composition which was subjected to moderate weathering during late Palaeozoic time. These sediments were deposited in basin situated at passive margin.
