The location map of the Dharwar Craton. The shaded area represents the Dharwar Craton. Generated from GeoMapApp (Ryan et al., 2009). [1]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.
Localized geology and geomorphology topics for various parts of the Himalaya are discussed on other pages: Geology of Nepal; Zanskar is a subdistrict of the Kargil district, which lies in the eastern half of the Indian union territory of Ladakh. Indus River - the erosion at Nanga Parbat is causing rapid uplifting of lower crustal rocks; Mount ...
Cleavage foliations may result due to stress-induced solution transfer by the redistribution of inequant mineral grains by pressure solution and recrystallization. [1] This would also help to increase rotation of elongate and tabular mineral grains. Mica grains undergoing solution transfer will align in a preferred orientation.
The Central Geological Service (formerly Geology stream of GSI) was constituted as an Organized Group ‘A’ Gazetted Service as per DOPT OM No. I-11019/12/2008-CRD dated 19/11/2009 by the Cadre Controlling Authorities. GSI is organized group 'A' service since 1982 as per DoPT O.M.No.5/12/79-PP-II dated 31.07.1982 and schedule -I.
This sequence occurred last on 4 March 2012, the previous having taken place four years before, in July 2008. [ 5 ] About 13,000 years ago in North America, the Cordilleran Ice Sheet crept southward into the Idaho Panhandle , forming a large ice dam that blocked the mouth of the Clark Fork River , creating a massive lake 2,000 feet (600 m) deep ...
In 1992, Coffin and Eldholm initially defined the term "large igneous province" as representing a variety of mafic igneous provinces with areal extent greater than 100,000 km 2 that represented "massive crustal emplacements of predominantly mafic (magnesium- and iron-rich) extrusive and intrusive rock, and originated via processes other than 'normal' seafloor spreading."
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 Ninety East Ridge at the centre of the picture and the Chagos-Laccadive Ridge on the upper left side. The Ninety East Ridge (also rendered as Ninetyeast Ridge, 90E Ridge or 90°E Ridge) is a linear intraplate rise on the Indian Ocean floor named for its near-parallel strike along the 90th meridian at the center of the Eastern Hemisphere.
