Energy Exploration & Exploitation, 2014 The method of amplitude-variation-with-angle (AVA) inversion was applied to estimate hydrate and gas saturations along bottom simulating reflector (BSR) at the Makran Accretionary Prism, Iran. Two AVA approximations were used to calculate their corresponding AVA attributes were compared to each other.

Appraisal of gas-hydrate/free-gas from VP/VS ratio in the Makran accretionary prism
Marine and Petroleum Geology, 2008Existence of gas-hydrate in the marine sediments elevates both the P- and S-wave seismic velocities, whereas even a small amount of underlying free-gas decreases the P-wave velocity considerably and the S-wave velocity remains almost unaffected. Study of both P- and S-wave seismic velocities or their ratio (VP/VS) for the hydrate-bearing sediment ...

<p>Long-term tectonics numerical modelling at accretionary margin scale is a powerful tool to retrieve the influence of many parameters such as the spatial variations of the frictional properties along a simplified interface and its feedback on the deformation.

The hydrate-bearing sediments above the bottom simulating reflector (BSR) are associated with low attenuation or high quality factor (Q), whereas underlying gas-bearing sediments exhibit high attenuation. Hence, estimation of Q can be important for qualifying whether a BSR is related to gas hydrates and free-gas.

AbstractSubduction zone accretionary prisms are commonly modeled as elastic structures where permanent deformation is accommodated by faulting and folding of otherwise elastic materials, yet accretionary prisms may exhibit other deformation styles over relatively short time scales.

Seismic reflection data from the Makran continental margin indicate the presence of a strong and widespread bottom simulating reflector (BSR). We apply a nonlinear full waveform inversion technique to multichannel reflection data from this area, to investigate the detailed velocity structure and hence the origin of the BSR.

Abstract We present paleomagnetic data from two overturned kink folds with horizontal axes, located NW of the Makran accretionary prism, southern Iran. In each one of these structures, the subvertical and the overturned limbs have been sampled in order to perform a fold test.
