Simplified geological map of the Dharwar Craton, which shows the western, central and eastern blocks. Modified from Jayananda et al., (2018). [2]As the Dharwar Craton is located in southern India, it is geographically surrounded by the Arabian Sea, the Deccan Trap, the Eastern Ghats Mobile Belt and the Southern Granulite Belt.
Peninsular Gneiss or Peninsular Gniessic Complex are the gneissic complex of the metamorphics found all over the Indian Peninsula, on top of which, the supra-crustal Dharwar System have been laid down. [1] The term was first fashioned by W.F.Smeeth of the Mysore Geological Department in 1916 based on the first scientific study of this rock ...
Due to continental drift, the India Plate split from Madagascar and collided with the Eurasian Plate resulting in the formation of the Himalayas.. The earliest phase of tectonic evolution was marked by the cooling and solidification of the upper crust of the earth's surface in the Archaean Era (prior to 2.5 billion years) which is represented by the exposure of gneisses and granites especially ...
The Dharwar craton with its characteristic Archaean volcanic - plutonic belts surrounded by the vast gneissic terrain. The southern granulite - gneiss terrain of Tamil Nadu - Kerala. The Eastern Ghat Mobile Belt (EGMB) along the east coast. The intra-cratonic "Purana" basins with thick sequences of platform facies rocks and/or rift related ...
The Aravalli Range (also spelled Aravali) is a mountain range in Northern-Western India, running approximately 670 km (420 mi) in a south-west direction, starting near Delhi, passing through southern Haryana, [1] Rajasthan, and ending in Ahmedabad Gujarat.

Deccan Traps in India geology zones. Because of its magnitude, some scientists (notably Gerta Keller) have speculated that the gases released during the formation of the Deccan Traps played a major role in the Cretaceous–Paleogene (K–Pg) extinction event (also known as the Cretaceous–Tertiary or K–T extinction).

The Vindhyan Basin is located on the southeastern side of the Aravalli Mountain Range where its formation is believed to be associated to the large downwarp of the crust after Delhi Orogeny. [9] It spans an area of about 104,000 km 2 in the northwestern part of India overlying on the Archean Bhilwara Gneissic Basement. [ 17 ]
