Abstract

A detailed grain size analysis of lower Gondwana sandstones in central part of Godavari Basin was undertaken to extract geologic information from the statistical parameters. The lower Gondwana sandstones are coarse to fine grained, moderate to poorly sorted, positively skewed and leptokurtic to mesokurtic. The variation in mean, sorting, skewness and kurtosis indicates change in environmental conditions in space and time. Multigroup discriminate analysis, bivariant grain size parameters and log probability plots indicate that the depositional environment of the lower Gondwana sandstones closely resembles that of modern fluvial sands.
