Representative seismic sections with geological interpretation overlay illustrating the main aspects of basin structure. (A) North–south line A–A’. The shallow, inverted northern portion of the basin has never been buried as deeply as the south and is characterized by the presence of large, tilted fault blocks with very shallow Fatehgarh and Barmer Hill Formation reservoirs. By contrast, reservoirs in the southern part of the basin are at burial depths present day of ca. 3 km and have not been significantly inverted. The large, deep fault northwest of the Vandana area is a major hinge line, controlling deposition through time and a pivot point north across which there has been strong inversion. (B) West–east line B–B’ showing asymmetric half graben structure and the steep-sided nature of the Airfield High.
