The Gondwana rocks of Singrimari area are dominantly arenaceous lithounits. The rocks are represented by diverse lithological variations and good preservations of sedimentary structures. Seven lithounits have been identified after field and megascopic observations. The lithofacies architecture of the succession is interpreted to reconstruct the depositional environment which ranges from point bar to channel bar of braided river system. The plant fossil remains are of Glossopteris flora. Both leaf and stemparts have been discovered from the carbonaceous shale layer. From the overall characters show the similarities with Lower Gondwana rocks.

The age is suggested to be Permo-carboniferous on the basis of plant remains and lithological characters.
