The Indian subcontinent is a repository of Archean cratonic nuclei with plethora of geoscientific data to better understand the early Earth evolution and the operating processes. The Bundelkhand Craton (BuC) in the north-central India is one of the five Archean cratons which preserves signatures of Paleoarchean magmatism, Archean subduction, Neoarchean metamorphism, spectacular craton-scale landforms as a testimony of Paleoproterozoic episodic silico-thermal fluid activity and plume-generated mafic magmatism, and a Paleoproterozoic meteoritic impact event, currently the seventh oldest in the world. Based on available geological and geophysical data, the BuC has been divided into north BuC (NBuC) and south BuC (SBuC) across the Bundelkhand Tectonic Zone (BTZ). The evolution of BuC has many similarities with other Indian cratons and the available geochronological data suggest that it forms a part of the Ur Supercontinent.
