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 ...
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 ...
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 ...
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 Gangapur Formation is a geological formation in Telangana, India. The Gangapur formation is Early Cretaceous in age. It forms a part of the Pranhita–Godavari Basin and overlies the Jurassic Kota Formation. The outcrops near the Gangapur village was first described in 1881 as the Gangapur beds. [1]
Greenstone belts are primarily formed of volcanic rocks, dominated by basalt, with minor sedimentary rocks inter-leaving the volcanic formations. Through time, the degree of sediment contained within greenstone belts has risen, and the amount of ultramafic rock (either as layered intrusions or as volcanic komatiite ) has decreased.
A fact from Dharwar Craton appeared on Wikipedia's Main Page in the Did you know column on 15 January 2022 (check views).The text of the entry was as follows: Did you know... that the oldest rocks of the Dharwar Craton are tonalite–trondhjemite–granodiorite gneisses and greenstone sequences between 3 and 3.4 billion years old?
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 ]
