When the Indian Plate mobbed northward after breaking off from the rest of Gondwana, it passed over a geologic hotspot, the Réunion hotspot, which caused extensive melting underneath the Indian craton. Geological Setting Bundelkhand Craton (BC) is not only an oldest part of the Indian shield area but also exist greenstone. 2 billion years old to 1. The magmatic event stratigraphy of the eastern Indian Shield (Banerjee, 1982; Alvi and Raza, 1992) is presented in Table 1. Structural geology, U-Pb zircon geochronology, and tectonic evolution of the Shillong Plateau and its neighboring regions in NE India. Cratons are large regions of continental crust that have remained tectonically stable for a prolonged period of time, often a billion years or more. Dingeldey (1996); The Kaoko belt (Namibia): Part of a late Neoproterozoic continental-scale strike-slip system. These rocks provide an excellent opportunity to study the origin ofthese rocks and their role in the formation and evolution of the continental crust in the Bastar craton. Age and Basin Evolution of the Cuddapah Supergroup 9 A period of potassic magmatism produced kimberlite dykes which intruded the Dharwar Craton and the Nallamalai Group of the Cuddapah Basin (Chalapathi Rao et al. Cyient Limited, Plot 11, Software Layout, Infocity, Madhapur, Hyderabad, India. The cratonic rocks are metamorphic and igneous, while the overlying sedimentary rocks are composed mostly of limestones, sandstones, and shales.

BC-Bhandara Craton; GPB- Godavari Proterozoic Belt. ; Shalivahan, Bimalendu B. The Bundelkhand craton is nestled in the northern margins of Peninsular India. There was an intermediate rifting phase during Paleo-Mesoproterozoic period when con-temporary basins formed over the rifted platform of the Indian cratons. When the Indian Plate mobbed northward after breaking off from the rest of Gondwana, it passed over a geologic hotspot, the Réunion hotspot, which caused extensive melting underneath the Indian craton. It is one of the best-studied terrains of Peninsular India. An analysis of lineaments and mineral occurrences of Veligallu Schist Belt and surroundings, Eastern Dharwar Craton, India using Remote Sensing & GIS. The first three events also occurred in the northeastern Indian craton, while the last is unique to the Hima laya.
