  2. Dharwar Craton - Wikipedia

    en.wikipedia.org/wiki/Dharwar_Craton

    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 ...

  3. Craton - Wikipedia

    en.wikipedia.org/wiki/Craton

    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 ...

    en.wikipedia.org/wiki/Geology_of_India

    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 ...

  5. Paleogeography of the India–Asia collision system - Wikipedia

    Drainage patterns provide clues not only to hydrological conditions, but also to geology and tectonic evolution. Burbank (1992) [42] proposed a model to explain how uplift driven by different factor can result in different drainage patterns, where uplifting is the upward movement of landmass with reference to the Earth's center.

    Apart from catapulting the Dharwar Craton onto the canvas of global Precambrian terranes, Mahmood Naqvi's studies contributed new dimensions and leads toward unraveling several basic problems in Precambrian geology especially the relevance of uniformitarianism and paradigms such as plate tectonics to the early geologic history of the earth. He ...

  7. Greenstone belt - Wikipedia

    en.wikipedia.org/wiki/Greenstone_belt

    Archaean plate tectonics did not take place on mature crust and as such the presence of thrust-in allochthonous greenstone belts is expected. By the Proterozoic, magmatism was occurring around cratons and with established sedimentary sources, with little recycling of the crust , allowing preservation of more sediments.

  8. Orogenic gold deposit - Wikipedia

    en.wikipedia.org/wiki/Orogenic_gold_deposit

    [42] [43] The next period of time for favorable orogenic gold deposit formation was 2.8-2.55 Ga in the greenstone belts of the Yilgarn craton, Superior province, Dharwar craton, Zimbabwe craton, Wyoming craton and Baltic shield.

  9. Zimbabwe Craton - Wikipedia

    en.wikipedia.org/wiki/Zimbabwe_craton

    The Limpopo belt formed contemporaneously with the Zimbabwe and Kaapvaal cratons, but remained geologically active until much later. It was only in the late Archean, ca. 2.8-2.5 Ga., that the two cratons were stabilized together and that high-grade metamorphism ceased in the Limpopo Belt. North of the Zimbabwe Craton is the Zambezi Belt. [2]
