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 ...
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 ...
Geology The river basin ... The two major groups of rocks found in the Sharavati river basin are the Dharwar system and the peninsular gneiss. [2] The Dharwar system: ...
Cratons of South America and Africa during the Triassic Period when the two continents were joined as part of the Pangea supercontinent. A craton (/ ˈ k r eɪ t ɒ n / KRAYT-on, / ˈ k r æ t ɒ n / KRAT-on, or / ˈ k r eɪ t ən / KRAY-tən; [1] [2] [3] from Ancient Greek: κράτος kratos "strength") is an old and stable part of the continental lithosphere, which consists of Earth's two ...
One of the oldest rock types of the state of Karnataka is named after Sargur. In geological terms it is called "Sargur supracrustals" or "Sargur schist" (about 3,300 to 3,000 million years old), an older formation of the two Precambrian craton formations, the other younger formation is the Dharwar Supracrustal rock (about 3,000 to 2,600 million year old).
Visitors can check out the geology at Sun Lakes and Dry Falls State Park between Soap Lake and Coulee City and enjoy nearly 75,000 feet of freshwater shoreline at the foot of Dry Falls.
This is followed by the Precambrian granites and gneisses of the eastern Dharwar Craton, sandstones, shales and limestones of the Gondwana Supergroup, various sedimentary units of Cuddapah and Vindhyan basins, charnockites and khondalites of the Proterozoic Eastern Ghats Mobile Belt and the sandstones of the Rajahmundry Formation.
