Abstract

The stratigraphic and tectonic setting in the north-eastern part of Himalayan belt is complex, thrusted and faulted due to the collision of Indian plate and the Burmese plate. Subsurface heterogeneity in such kind of geologically complex and logistically hostile terrain of Assam-Arakan Basin specifically in the area falling in Mizoram state is one of the key factors for the hydrocarbon exploration. The study area is located in the Mizoram state and forms a part of Arakan-Yoma mountain fold belt. Seismic technique is the best among the other geophysical techniques for hydrocarbon exploration; however seismic imaging in such kind of complex mountainous, thrusted and faulted terrain have always problems for both the acquisition and data processing point of view to map the deeper basement configuration. This happens due to the very meager energy transmission in this complex area with dipping beds. To overcome such type of problems, it was always recommended to carry out some passive geophysical survey to provide value added constraints for integrated interpretation.
