Abstract. The Precambrian Peninsular India is comprised of a few ancient cratonic nuclei that were formed during prolonged geological history during Archean to Paleoproterozoic and are classified into two blocks: The North Indian Block (NIB) and the South Indian block (SIB) (Naqvi and Rogers 1987).The former comprises of the Bundelkhand and Aravalli Cratons and the latter is made up of the. These cratons are: the Dharwar or Karnataka craton, Bastar (also called Bhandara) craton, Singhbhum (-Orissa) craton, Chhotanagpur Gneiss Complex (which is arguably a mobile belts of some workers), Rajasthan craton (Bundelkhand massif included), and Meghalaya craton The cratons or microplates collided and developed the fold belts that occur peripheral to the cratonic areas of the Indian shield
Cratons and Fold Belts of India, is a unique attempt at presenting geological characteristics and evolution of the fold belts and the cratonic areas of the Indian shield The E-W and N-S arrows in north India indicate Meso-Neoproterozoic convergence between the Bundelkhand craton (BKC) and Marwar block across the Aravalli-Delhi Mobile Belt (ADMB) and BKC and Bhandara craton (BC) across the Satpura Mobile Belt (SMB), respectively while the NE-SW arrow is the resultant of these two converging forces during that time The Indian Craton remained attached to Gondwana, until the supercontinent began to rift apart about in the early Cretaceous, about 125 million years ago (ICS 2004). The Indian Plate then drifted northward toward the Eurasian Plate, at a pace that is the fastest known movement of any plate
Cratons are stable because they are strong. The geology of the Himalayas illustrates this - the modern day plate boundary between Indian and Asia is at the southern edge of the Himalayas. The cratonic Indian plate is barely deformed, in great contrast to the vast pile of deformed soft young crust in the Tibetan Plateau to the north From Wikipedia, the free encyclopedia A craton is an ancient part of the Earth's continental crust which has been more or less stable since Precambrian times. Cratons whose ancient rocks are widely exposed at the surface, often with relatively subdued relief, are known as shields Cratons and Fold Belts of India, is a unique attempt at presenting geological characteristics and evolution of the fold belts and the cratonic areas of the Indian shield. The author has evaluated the different evolutionary models for each fold belt in light of all the currently available geological and geochronological informations that are.

In contrast, Pisarevsky et al. (2003) show only one indication for late Grenville-age granitoid that, on palaeomagnetic grounds, the Congo/Sa˜o magmatism in southern India, and this comes from Francisco Craton was far removed from the other strongly discordant zircons of a granite - gneiss xeno- continental masses making up Rodinia (see Fig. Geological Survey of India 3 geologically constituted of Dharwar Craton comprises of greenstone-granite belts, gneisses and granulites. Greenstone belts essentially consist of meta-volcano-sedimentary sequences, surrounded and dissected by Peninsular Gneiss. At the southern end of the craton these give way to granulite suite of rocks The Bastar Craton of India is composed of Archaean nuclei of tonalite-trondhjemite-granodiorite gneisses, enveloped by an older granite-greenstone belt (>3000 Ma) with banded iron formation (BIF), and an auriferous younger granite-greenstone belt with BIF Occupies 20% of the area of the Precambrian of the Peninsular India. 4. Proterozoic sedimentary basins are divided into 2 types based on age: (a).Paleoproterozoic basins: 1.Bijawar and Sonrai basins Bundelkhand and Harda Inlier craton 2.Gwalior basin 3.Abujhmar basin Bastar craton 4.Papaghni sub-basin Dharwar craton [Cuddapah basin] 5
1. The Dharwar craton The Late Archaean Dharwar craton (figure 1), in the sense of Ramakrishnan (1993), is an important part of the collage of Archaean and Proterozoic terrains in Peninsular India. Areas east and south of the craton are characterized by structures, metamorphism an and geochronology of six Indian cratons of which Aravalli and Bundelkhand are located to the north of nearly E-W trending Central Indian Tectonic Zone (CITZ) and Dharwar, Bastar, Singhbhum and Meghalaya are towards the south of the zone. The Aravalli craton with 3.3 Ga old basement of the Banded Gneissic Complex (BGC) is divide CRATON The Bundelkhand craton is one of four Archean shields (Dharwar, Singhbhum, Aravalli, and Bundelkhand) in India (Fig. 1a). The Bundelkhand shield occupies nearly 29,000 km 2 in the Central Indian Shield region (Fig. 1b); it consists of supracrustal gneisses with or without tonalite-trondhjemite
The northern margin of the Indian craton has been variously considered to consist of a passive margin south of the Yarlung-Tsangpo suture (Myrow et al., 2003), or early Paleozoic accreted terranes (DeCelles et al., 2000), or Late Jurassic to Early Cretaceous juxtaposed suspect terranes (Martin, 2017).However, van Hinsbergen et al.

A craton always contains the oldest rocks within its host continent, and it typically has ages older than 2.5 billion years, from a geologic era known as the Archean. Common usage has evolved so that the term craton often implies the Archean portion. But strictly speaking, cratons are not limited to the Archean era What is a craton? A craton is a large, coherent domain of Earth's continental crust that has attained and maintained long-term stability, having undergone little internal deformation, except perhaps near its margins due to interaction with neighbouring terranes. Stable continental crust is an end product of intense magmatic, tectonic, and metamorphic reworking; hence, cratons consist of. The eastern margin of the Chitradurga Schist Belt is widely believed as the dividing line of Dharwar Craton (DC) into Western Dharwar Craton (WDC) and Eastern Dharwar Craton (EDC). This study aims at re-defining the division of DC based on pronounced gravity high encompassing Chitradurga Schist Belt of WDC and Closepet granite to Ramgiri-Penackacherla Schist Belt of EDC The Precambrian Dharwar Craton of Peninsular India comprises three distinct crustal domains, namely the Western Dharwar Craton (WDC), the Eastern Dharwar Craton (EDC) and the Eastern Ghats Mobile Belt (EGMB). The domain boundaries are demarcated by bipolar (positive and negative) gravity anomalies, measured along a 600 km long Udipi-Kavali seismic line
The Singhbhum craton of northeastern India (Fig. 1a, b) contains one of the oldest rock successions in the world (Saha, Reference Saha 1994; Mukhopadhyay, Reference Mukhopadhyay 2001) comparable in age only with the Isua Greenstone Belt of Greenland, the Abitibi Belt of Ontario and Quebec, the Coonterunah Group of the Pilbara craton and the. Several late-collision and intraplate features are not entirely integrated in the classical plate tectonic model. The Pan-African orogeny (730-550 Ma) in Saharan Africa provides some insight into the contrasting behaviour of cratons and mobile belts. Simple geophysical considerations and geological observations indicate that rigidity and persistence of cratons are linked to the presence of a. εSr i vs εNd i for the Dharwar Craton kimberlites and Cuddapah Basin lamproites, southern India.

The paleomagnetic pole position for the Singhbhum craton at 2.25 Ga is 22°N, 126°E (A95=9°).
