  1. Jun 1, 2001 · During early upper Vindhyan time, the E–W elongated basin tilted northward and this coincided with kimberlite intrusion and basin-wide volcanism, albeit of limited scale. The basin-wide unconformity-bounded Vindhyan Supergroup is divided into two sequences by an unconformity (laterally correlatable with a conformity) that owes its origin to the transitory compression.

  2. Jun 18, 2022 · The Vindhyan Supergroup can be divided into the lower and upper Vindhyan sequences, composed of sandstone, shale, carbonates and some conglomerate and volcaniclastic beds. Economic minerals found in the Vindhyan Basin include diamonds, pyrite, coal, limestone and building stones. The Vindhyan Supergroup provides important geological information ...

  3. Sedimentation in the Upper Vindhyan started after a prolonged depositional hiatus marked by the Dulchipur Conglomerate at the base of Kaimur Group (Kumar et al., 2002; Tripathi and Singh, 2015). Compared to the Lower Vindhyan, the Upper Vindhyan is mostly dominated by siliciclastic sequences with carbonate units occurring at the top. Presence

  4. Mar 29, 2019 · The Vindhyan Basin of western India is a part of the largest Proterozoic sedimentary basin of the Indian subcontinent. Deposited in a largely shallow marine environment, the sedimentary sequence of the basin, known as the Vindhyan Supergroup, is believed to hold clues to our understanding of the evolution of life and climate during the Proterozoic.

  5. Mar 1, 2017 · The Vindhyan Supergroup of India is one of the largest and thickest sedimentary successions of the world. Deposited in an intra-cratonic basin, it is composed mostly of shallow marine deposits. It is believed to have recorded a substantial portion of Proterozoic time and therefore, likely to contain valuable information on the evolution of the ...

  6. The Vindhyan basin, developed during the Palaeo to the Neoproterozoic time (Bose et al. 2001;Chakra-borty et al. 2010), rests unconformably on the Ara-valli craton, the Bundelkhand granitic gneiss and the Mahakoshal group of rocks. The Vindhyan rocks are distributed over *1,00,000 km2. The Vindhyan sediments are generally unmetamorphosed and only

  7. Mar 1, 2015 · This chapter attempts an understanding of the Proterozoic Vindhyan Basin history in the broad framework of central India. Although the entire Vindhyan Supergroup is within the scope of this work ...
