Channel Sandstone Bodies in Fluvial Permian - Triassic Gondwana Succession of Peninsular India

Two types (I and II) of channel sandstone bodies are recognised in the fluvial Permian - Triassic Gondwana succession of peninsular India on the basis of geometry, associations and sedimentary structures. Irrespective of geometry and associations, these channels are oriented towards northwest, comparable with the Permian - Triassic paleoslope. The geometry, hierarchy of sedimentary structures and association of these channel bodies suggest channel aggradation, and lateral accretion in crevasse channels, respectively for the deposition of Type-I and Type-II channel sandstone bodies.
