Proterozoic Vindhyan Basin: configuration and evolution
(2025-04-02) Bose,P. K. et all
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, particular attention is paid to the little-known northwestern fringe exposures. Distinctive facies assemblages and diverse palaeocurrents in these exposures of the Lower Vindhyan play a pivotal role in the interpretation. Analysis of outcrop and subsurface data that extend under the Gangetic alluvium to the north of the Vindhyan out-
crops further supports the hypothesis that an east– west-elongated basement ridge initially separated the master Vindhyan Basin from smaller contemporary basins to the north. Deposition took place in isolated lacustrine and fluvial basins north of the divide and largely in a marine realm south. Dextral shear accompanying rifting generated ridges that criss-crossed the Lower Vindhyan seafloor to the south. The uniform character of the Upper Vindhyan throughout, nevertheless, testifies to later drowning of the divide and unifica-tion of all of the basins as a consequence of regional tilt northward. However, the extended Vindhyan Sea was restricted by a second east–west-elongated ridge from merger with the contemporary Proterozoic sea further north, disparate sediments of which have been encoun-tered in a few drill cores only.
School Dropout of Girls: A Study on Selected Indian States
(Emerald Publishing Limited, 2025-03-01) Mishra,Tanusree; Banerjee (Chatterjee), Tanmoyee
Exploration of District Level Household Survey 4 data show that among
the selected states, Karnataka, West Bengal, Meghalaya, Tripura, Telengana, Arunachal Pradesh and Andhra Pradesh show higher rates of school
dropout of girls compared to the all India level. Using multilevel probit
technique, the study shows that the incidence of school dropout of girls decreases if the first born of the parents is male and mother is more educated
than father while it increases with lower asset endowment, land-holding
and high spousal age-gap between parents. Further it is high among the
Muslim religion and schedule caste category.
