The Precambrian rocks of India have been classified into two systems, namely the Dharwar system and the Archaean system (gneiss and schists). The Dharwar System. The rocks of the Dharwar system are mainly sedimentary in origin, [8] and occur in narrow elongated synclines resting on the gneisses found in Bellary district, Mysore and the Aravalis ...
Exposed gneiss hillock at Lal Bagh Geological Map of South India – The Dharwars of South India. The Archean gneisses and schists, which are the oldest rocks of the Indian Shield, constitute a considerable area of Peninsular India. The Dharwar (Super Group) and the Peninsular Gneissic Complex are the classified groups of the Precambrian rocks ...
The Deccan Traps are famous for the beds of fossils that have been found between layers of lava. Particularly well known species include the frog Oxyglossus pusillus (Owen) of the Eocene of India and the toothed frog Indobatrachus, an early lineage of modern frogs, which is now placed in the Australian family Myobatrachidae.

Jodhpur Group-Malani Igneous Suite Contact of Aravalli range is a geological feature representing the last phase of igneous activity of Precambrian age in the Indian Subcontinent at the foot of the picturesque Mehrangarh Fort in Jodhpur city, the second largest city in Rajasthan after Jaipur.
Granite is an igneous rock, which means it formed from magma, or melted rock. It forms deep inside the Earth under a mountain or volcano when melted rock cools or crystallizes into solid rock. Over time, wind, ice, and water wear away at the mountain or volcano above it, and the granite is exposed to the surface.
The Rajmahal Traps is a volcanic igneous province in Eastern India, covering the parts of Jharkhand, West Bengal and Meghalaya. The Rajmahal Hills of Jharkhand is the type area of this province. Multiple layers of solidified lava made the 608-metre-thick (1,995 ft) Rajmahal Traps which are dipping 2–5° towards the north-east. Individual ...

The Deccan Traps in the north west were formed by multiple layers of igneous rocks laid down by basaltic lava flows following a massive volcanic eruption that occurred during the end of the cretaceous period (66 mya). The underlying bed consists of granite and sedimentary rocks formed during the precambrian era and the formation of Gondwana.
