The Dharwar Craton is an Archean continental crust craton formed between 3.6-2.5 billion years ago , which is located in southern India and considered the oldest part of the Indian peninsula. [ 2 ] Studies in the 2010s suggest that the craton can be separated into three crustal blocks since they show different accretionary history (i.e., the ...
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 ...
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 ...
Dharwar Craton (Karnataka Craton), 3.4 - 2.6 Ga, granite-greenstone terrain covers the state of Karnataka and parts of eastern and southern Maharashtra state, and forms the basis of the southern end of the Deccan Plateau. In 1886 it was divided into two tectonic blocks, namely Eastern Dharwar Craton (EDC) and Western Dharwar Craton (WDC).
Geological evidence of rocks younger than 59 Ma and deposited on top of the turbidite sequence can be considered as indicators to reconstruct tectonic evolution after collision had begun. Various evidence documented along NE-SW and NW-SE sections of the India–Asia collision zone synchronize with each other, being in favour of a "one-off ...
A craton is an ancient stable continental block. [13] Also, a craton has survived from plate tectonics that pull apart, collide or tear continents. [ 13 ] On average, the felsic volcanic rocks only contribute to ≈15-20% in volcanic rocks of greenstone belts. [ 6 ]
[42] [43] The next period of time for favorable orogenic gold deposit formation was 2.8-2.55 Ga in the greenstone belts of the Yilgarn craton, Superior province, Dharwar craton, Zimbabwe craton, Wyoming craton and Baltic shield.
The epilogue of the tectonic evolution was marked by granitic and rhyolitic magmatic events, namely the emplacement of the Erinpura granite and the Malani Volcanics on the western side of Aravalli-Delhi orogenic belt. [4] This event is ranked third among the largest igneous province in the globe, with a total area of about 52,000 km 2 in India. [9]
