A number of magnetic zones, faults, lineaments and domal structures were interpreted based on the analysis of aeromagnetic data. Magnetic basement depth and thickness of the sediments were computed by means of quantitative interpretation techniques. A number of alternate basement ridges/highs/uplifted blocks and depressions/lows/downthrown blocks were also delineated. The lithological variations, major folding and faulting patterns, circular spectral anomalies and other geological structures were interpreted from IRS-1C satellite data. The tectonic framework and deformational history of the basin were deduced. The results obtained from the interpretation of aeromagnetic and satellite data were then integrated and the potential zones of hydrocarbon deposits and vulnerable areas for earthquake occurrence were derived.

Abstract


A number of magnetic zones, faults, lineaments and domal structures were interpreted based on the analysis of aeromagnetic data. Magnetic basement depth and thickness of the sediments were computed by means of quantitative interpretation techniques. A number of alternate basement ridges/highs/uplifted blocks and depressions/lows/downthrown blocks were also delineated. The lithological variations, major folding and faulting patterns, circular spectral anomalies and other geological structures were interpreted from IRS-1C satellite data. The tectonic framework and deformational history of the basin were deduced. The results obtained from the interpretation of aeromagnetic and satellite data were then integrated and the potential zones of hydrocarbon deposits and vulnerable areas for earthquake occurrence were derived.
