Lateral variation in gravelly sediments and processes in an alluvial fan-fan-delta setting,north of Durgapur

Sedimentological study of the digitated lobes of gravel and associated sediments in the north of Durgapur results in identification of five major facies. Facies analysis indicates the sediments were deposited from an alluvial fan that has prograded in to an inferred shallow body of water. The analysis also suggests debris flow deposits dominate proximal part, modified grain flow and turbidity current the middle part and current generated channel and non-channel deposits in the distal part of the alluvial fan — fan-delta sequence.
