Singhbhum craton (SC) is one of the oldest (~3.6 Ga) cratonic nuclei of the Indian shield that presents a complex evolutionary history involving episodic sedimentation, poly-phase magmatism and orogenesis. Reconstructing the evolutionary history of this craton and its peripheral regions is necessary for tracing the history of Archaean continents, their amalgamation, evolution and dispersion. Geochemical studies carried out for SC suggest Neoarchaean and Mesoarchaean ages for the Older Metamorphic Gneiss (OMG), Older Metamorphic Tonalitic Gneiss (OMTG) and the Singhbhum Granite (SG).
