摘要

Seismic reflection profiles across many continental margins have imaged bottom-simulating seismic reflectors (BSRs), which have been interpreted as being formed at the base of a methane hydrate zone. These reflectors might arise from an impedance contrast between high velocity layers, partially hydrated sediments overlying gas/water-saturated sediment. Our study was aimed at amplitude analysis and its relation with velocity on one of the profiles on the western continental margin of India. In our data BSR is found to be discontinuous in the profile and amplitude blanking is seen above the BSR. To get an idea about amplitude in the region with and without BSR, we have performed both amplitude and velocity analysis. The relation between amplitude variation and velocity variation is utilized to estimate range of velocity in the blanked zone.
