Abstract:

The fine-grained samples of the shales from the Sojat formation of Punagarh belt are selected for the purpose of the geochemical studies in order to understand the provenance, paleoweathering conditions and tectonic conditions. The A-CN-K ternary diagram and chemical index of alteration (CIA) values are used to suggest that granitic source rocks underwent moderate to high degree of chemical weathering under moderate weathering conditions in the humid and warm climate during the Proterozoic period. There are the various geochemical discriminate and elemental ratios such as K2O/Na2O, Al2O3/TiO2, SiO2/Al2O3, La/Sc, Th/Sc, Ti/Zr and REE abundances and their ratios with pronounced negative Eu anomalies suggest that these rocks be the product of predominantly felsic in nature consisting of granitic and TTG with subordinate mafic material. The shales of the Sojat formation are from passive to active tectonic setting based on the trace element ratios and La-Th-Sc ternary diagram.
