Abstract The Marwar Supergroup refers to a 1000–2000 m thick marine and coastal sequence that covers a vast area of Rajasthan in NW–India. The Marwar Basin uncomformably overlies the ∼750–770 Ma rocks of the Malani Igneous Suite and is therefore considered Late Neoproterozoic to Early Cambrian in age. Upper Vindhyan basinal sediments (Bhander and Rewa Groups), exposed in the east and ...
25-04-2010· In the northwest of the Aravalli Mountain Range, the Marwar Supergroup occupies large area in Rajasthan which was earlier referred to as the Trans-Aravalli Vindhyans, ().It is represented by a thick pile of sediments made up of sandstones, shales, carbonates, and evaporites occupying an area of about 51,000 sq. km (Paliwal, 2007).The rocks are unmetamorphosed and undeformed and show …
Keywords: Marwar Supergroup, Nagaur Sandstone, trace fossils, trilobites. The Marwar Supergroup occupies a large area in north western Rajasthan and attains a thickness of more than 1000 m that unconformably overlies ca. 779-681 Ma old Malani Igneous suite1. As such the sediments of the Marwar Supergroup are considered younger than 680 Ma. No ...
Eastern Rajasthan is characterised by the vast sedimentary stretch constituting the Vindhyans, which is juxtaposed against the rocks of the Bhilwara Supergroup along the Great Boundary Fault. The northern and north-western parts of the State exhibit Upper Proterozoic-Early Cambrian rocks of the Marwar Supergroup which are overlain by sedimentary rocks of different ages of Palaeozoic and ...

The Marwar Supergroup, earlier known as the Trans Aravalli Vindhyans, is well exposed in the west of Ara valli Range in Rajasthan. It unconformably overlies the Malani Igneous Suite which has been dated as 779 681 Ma (ref. 4). The rocks are unmetamorphosed and undeformed. The Supergroup is subdivided into three

The Marwar Supergroup refers to the 1000-2000m thick marine and coastal sequences that cover a vast area of the Rajasthan shelf in NW-India. The Marwar Basin uncomformable overlies the well-dated ~750 Ma rocks of the Malani Igneous province and is therefore believed to be Late Neoproterozoic to Early Cambrian in age.
The Marwar Supergroup (MSG) occupies a large area of about ~51,000 km2 in the Jodhpur-Khatu-Nagaur-Bikaner areas of western Rajasthan (Paliwal, 2007). It is believed that the sedimentation either ended before the onset of Cambrian or during Lower Cambrian. As stated from the earlier literature, the Marwar Supergroup was considered as. Obtener ...
