Abstract

The study area falls in the Mizoram state in Assam- Arakan basin is highly undulating, complex terrain, deprived geometry with complex subsurface geology where basement depth varies more than 12 km. Due to difficult terrain and unapproachability, conventional seismic survey is difficult in this area and hence 2D crooked line seismic survey has been carried out for hydrocarbon exploration. However, due to complex subsurface, the quality of 2D crooked line seismic data is not proven to map the subsurface properly. Hence, to reduce the ambiguity, various geoscientific studies like gravity-magnetic, 3D seisloop seismic survey, geochemical, thermal imaging, geological modelling etc. have been carried out. Nevertheless, mapping of thrust and fault locations in such kind of hilly terrain and geologically complex areas always a difficult task for the geoscientists.
