Seismic attributes for identifying gas-hydrates and free-gas zones: application to the Makran accretionary prism

, 2009
The most commonly used marker for gas-hydrates is a bottom simulating reflector or BSR on seismic section. The BSR is not a lithological interface but a physical boundary between the gas-hydrates bearing sediments above and free-gas saturated sediments ...

Study on the Occurrence of Double Bottom Simulating Reflectors in the Makran Accretionary Zone

A Bottom Simulating Reflector (BSR) is a seismic feature closely related to marine gas hydrate as it is usually regarded as the seismic response of the base of the gas hydrate stability zone in seismic profiles.

Iranshahr blueschist: subduction of the inner Makran oceanic crust

, 2017
The Makran accretionary prism in SE Iran and SW Pakistan is one of the most extensive subduction accretions on Earth. It is characterized by intense folding, thrust faulting and dislocation of the Cenozoic units that consist of sedimentary, igneous and ...

Evidence for a thick free gas layer beneath the bottom simulating reflector in the Makran accretionary prism

, 2000
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 ...

Gas and fluid venting at the Makran Accretionary Wedge off Pakistan

, 2000
The Makran accretionary complex shows a distinct bottom-simulating reflector, indicating a thick gas-hydrate-bearing horizon between the deformational front and about 1350 m water depth which seals off the upward flow of gas-charged fluids.

Strain decoupling across the decollement of the Barbados accretionary prism

, 1996
The interrelation between deformation styles and behavior of fluids in accretionary prisms is under debate, particularly the possibility that overpressuring within the basal decollement may enable mechanical decoupling of the prism from the subducting

Common depth points and associated geographic coordinates, supplement to: Smith, GL et al (2014): Fluid generation and distribution in the highest sediment input accretionary margin, the Makran. Earth and Planetary Science Letters, 403, 131-143

Fluids in subduction zones can influence seismogenic behaviour and prism morphology. The Eastern Makran subduction zone, offshore Pakistan, has a very thick incoming sediment section of up to 7.5 km, providing a large potential fluid source to the ...

The structure, fluid distribution and earthquake potential of the Makran Subduction Zone, Pakistan

, 2013
The Makran subduction zone (offshore Pakistan and Iran) has the largest accretionary prism of any margin worldwide, formed due to the thick incoming sediment section of up to 7.5 km.
