Single channel airgun seismic reflection data from equatorial region of the Central Indian Basin (CIB) revealed some new information on the structure and stratigraphy of the deformed blocks in this area. The data from five (N-S and E-W) traverses and from a detailed grid over a 45 x 45 km block, covering the area between 2 degrees N and 2 degrees S, and 81 degrees and 84 degrees E, indicate (1) a NE-SW trend for the faulted deformed blocks; (2) presence of fracture zones older than and unrelated to the tectonics associated with the process of deformation; (3) an older age (> 17 Ma) for the base of the Bengal Fan turbidites; and (4) a thin layer of transparent probably pre-fan (pelagic) sediments immediately above the acoustic basement
