Exploration in Andaman Forearc Basin its Evaluation, Facies Trend and Prospects - A Review

P. C. Misra, T. K. Roy

Abstract

The paper reviews the exploration activities in the Andaman forearc basin. Structural analysis reveals various stages of evolution with corresponding sedimentation cycles. Subduction complex comprises accretionary prisms and forms the floor of the ponded Neogene sediments in the Upper trench slope and also the base of the young accretionary basins in the west of the Outer high. Unconformity overlying subduction complex is much younger in the Lower trench slope as compared to the east. Reliable and continuous reflections are absent within subduction complex. Favourable lithofacies trends vis-avis structural evolution of the area have been outlined. This has enabled to identify broadly the future hydrocarbon prospects in the region.
