The Late Palaeoproterozoic Mayong granitoids of Assam constitute an important component of the continental crust and the Basement Gneissic Complex in the northern extension of the Shillong Plateau, north‐east India. The basement rocks of Shillong Plateau are considered as a continuation of the Central Indian Tectonic Zone. In this study, emphasis is given on the new zircon U–Pb age, Hf isotopic composition,...
The Western Dharwar Craton (WDC) exhibits numerous exposures of NNW–SSE to NW–SE trending mafic dykes. Geochemistry of four 2.21 Ga NNW–NW trending dykes and 21 other similar trending dykes provides new insights into the geochemical behaviour, mantle source characteristics, and tectonic history of mafic magmatic event, which have also affected the Eastern Dharwar Craton (EDC). Based on modal mineralogy...
