Grain size analysis and depositional pattern of upper Gondwana sediments (Early Cretaceous) of Salbardi area, districts Amravati, Maharashtra and Betul, Madhya Pradesh

摘要

A detailed grain-size analysis of twenty-two sandstone samples from the uppermost Gondwana succession of Salbardi area has been carried out to interpret the depositional pattern. The sandstones are mainly medium to coarse grained, moderately sorted, near-symmetrical to fine-skewed and mesokurtic in nature. Inter-relationship of various parameters shows bimodal nature of sediments having dominance of medium sand. Based on the granulometric analysis, a fluvial environment of deposition is interpreted for the succession.
