Abstract

In Cachar fold belt, Assam, India, 22 Exposed and 6 concealed structures have been mapped till date. Banskandi, Bhubandar are concealed gas fields, the presence of which have been identified mainly based on geomorphic anomalies and seismic surveys. Present paper deals with the role of land sat imageries in firming up the concealed structures where the seismic data is poor(Fig:1). An attempt has been made in this in paper in quantifying the geomorphic anomalies by elevation contours derived from landsat image data. Google earth helped in quantifying the geomorphic anomalies by elevation contours. Geologic and seismic map overlays helped to a greater extent in integrating and firming the prospect.
