“…Based on the framework provided by Ramakrishnan and Vaidyanadhan (2008) and Meert et al (2010) and applying recent literature (including new age data) on the Dharwar craton encapsulated in a special issue of Precambrian Research (vol. 227, Jayananda et al 2013 and references therein), a preliminary evolution of the WDC can be put together.…”

Abstract:The geological history and evolution of the Dharwar craton from ca. 3.5-2.5 Ga is reviewed and briefly compared with a second craton, Kaapvaal, to allow some speculation on the nature of global tectonic regimes in this period. The Dharwar craton is divided into western (WDC) and eastern (EDC) parts (separated possibly by the Closepet Granite Batholith), based on lithologi-cal differences and inferred metamorphic and magmatic genetic events. A tentative evolution of the WDC encompasses an early, ca. 3.5 Ga protocrust possibly forming the basement to the ca. 3.35-3.2 Ga Sargur Group greenstone belts. The latter are interpreted as having formed through accretion of plume-related ocean plateaux. The approximately coeval Peninsular Gneiss Complex (PGC) was possibly sourced from beneath plateau remnants, and resulted in high-grade metamorphism of Sargur Group belts at ca. 3.13-2.96 Ga. At about 2.9-2.6 Ga, the Dharwar Supergroup formed, comprising lower Bababudan (largely braided fluvial and subaerial volcanic deposits) and upper Chitradurga (marine mixed clastic and chemical sedimentary rocks and subaqueous volcanics) groups. This supergroup is preserved in younger greenstone belts with two distinct magmatic events, at 2.7-2.6 and 2.58-2.54 Ga, the latter approximately coincident with ca. 2.6-2.5 Ga granitic magmatism which essentially completed cratonization in the WDC. The EDC comprises 2.7-2.55 Ga tonalite-trondhjemitegranodiorite (TTG) gneisses and migmatites, approximately coeval greenstone belts (dominated by volcanic lithologies), with minor inferred remnants of ca. 3.38-3.0 Ga crust, and voluminous 2.56-2.5 Ga granitoid intrusions (including the Closepet Batholith). An east-to-west accretion of EDC island arcs (or of an assembled arc -granitic terrane) onto the WDC is debated, with a postulate that the Closepet Granite accreted earlier onto the WDC as part of a "central Dharwar" terrane. A final voluminous granitic cratonization event is envisaged to have affected the entire, assembled Dharwar craton at ca. 2.5 Ga. When Dharwar evolution is compared with that of Kaapvaal, while possibly global magmatic events and freeboard-eustatic changes at ca. 2.7-2.5 Ga may be identified on both, the much earlier cratonization (by ca. 3.1 Ga) of Kaapvaal contrasts strongly with the ca. 2.5 Ga stabilization of Dharwar. From comparing only two cratons, it appears that genetic and chronologic relationships between mantle thermal and plate tectonic processes were complex on the Archaean Earth. The sizes of the Kaapvaal and Dharwar cratons might have been too limited yet to support effective thermal blanketing and thus accommodate Wilson Cycle onset. However, tectonically driven accretion and amalgamation appear to have predominated on both evolving cratons.Résumé : L'histoire géologique et l'évolution du craton de Dharwar (ϳ3,5-2,5 Ga) sont examinées et sommairement comparées a` celles d'un second craton, celui de Kaapvaal, afin de permettre une certaine spéculation sur la nature des régimes tectoniques globaux duran...

“…2 and 3). The cratonisation of India was polyphase, and a stable configuration of the assembly was completed by *2.5 Ga (Meert et al 2010). Several Meso-to Neoproterozoic Purana Basins that include the Cuddapah, Chhattisgarh, Vindhyan, Pranhita-Godavari, Indravati, Bhima-Kaladgi, Kurnool, and the Marwar basins cover the Archean-early Proterozoic terrains, and are spread over many parts of the Indian landmass (Figs.…”

“…A crustal-scale lineament, namely the Narmada-Son lineament separates the Bundelkhand Craton and the ADMB to its north from the Bastar and Singhbhum Cratons to its south (Naqvi and Rogers 1987). The supracrustal rocks of the Aravalli-Delhi Fold Belts overlie the 3.3 to 2.5 Ga old Banded Gneissic Complex (BGC), and their ages are considered between *1850 and 2150 Ma (Meert et al 2010).

Surrounded by the Himalayan Orogen, Indian Ocean, Bay of Bengal and Arabian Sea on its north, south, east and west, respectively, the Indian subcontinent represents more than 3.5 Ga of geological history spanning from the Archean to Quaternary. The exposed Precambrian basement of India comprises four Archean cratonic nuclei welded together by several Proterozoic mobile belts. Proterozoic intracontinental basins that contain mostly undeformed sedimentary successions unconformably overlie the basement. The basement rocks are covered in the north along the Himalayan front by thick deposits of the Indo-Ganga alluvium, and in the west central region by the end-Cretaceous Deccan flood basalts. Basins related with intra-to inter-continental rifting of the Indian craton viz. the Gondwana Basins and those of the east and west coast record the Phanerozoic history of India from Permian to Cenozoic. Since *55 Ma, the continent-continent collision between the northerly drifting Indian Plate and the Eurasian Plate has guided the development of the structural design of the Himalayan Orogen. These tectono-geomorphic processes were responsible for the first order relief structure of the northern part of the Indian subcontinent including the development of the topography of the spectacular Himalayan Orogen and its foreland.

“…Cratons present in the Indian peninsular are Dharwar Craton in the south, Bastar Craton in the central, Singhbum Craton in the east and Aravalli-Bundelkhand Craton in the west [5]. The Dharwar Craton is the largest craton in Indian peninsular having typical Archean greenstone-granite terranes with most of the major rock units ranging in age from Meso-to Neo-archean [6].…”

The Peddavura greenstone Linear Belt, NW-SE trending, is formed in the Eastern part of the Dharwar Craton of south India, extended over 62.5 sq•km in Nalgonda and Guntur districts region. The entire belt is illustrated as Peninsular Gneiss. The Belt Study has attracted geologists for conducting further research to evaluate the crust forming process at the time of early volcanic eruption of Earth's history. The South Indian Dharwar Craton depicts and exposes the crustal segments where geological activities took place consistently during the Precambrian. The PSB (Peddavura Schist Belt) mostly consists of meta volcanic (meta basalts), amphibolites, granites, dolerites, basaltic andesites, pegmatite and Banded Magnetite Quartzite's (BMQ) rock types. The 20 represented rock samples made for thin section studies. Based on the Petrological studies minerals are showing uralitization, saussuritization in the granite with mylonite structures, perthite and dolerite are showing heavy metal such as rutile and other opaque minerals (Magnetite, hematite, and typical pyrite crystal) are present in different represented rock samples. The minerals are showing different alteration zones along with microstructures. Using the Petrological studies the minerals and rock types are identified in the study region.
