Morphotectonics domains and structural styles in the Makran accretionary prism, offshore Iran
Sedimentary Geology, 2007Abstract The Makran accretionary prism is regarded as one of the most extensive subduction complex on Earth. It provides an ideal example of accretionary prism to study processes related to subduction at plate boundaries such as frontal accretion and underplating.

Sediment dewatering in the Makran accretionary prism
Earth and Planetary Science Letters, 1985Abstract Sediments within the Makran accretionary prism are considerably more compacted than the material entering the subduction zone due to the additional tectonic stresses resulting from plate convergence and accretionary processes. Tectonic compaction of the offscraped sediments has been documented by deriving in-situ porosities in the upper 4 km

Large-scale sediment underplating in the Makran accretionary prism, southwest Pakistan
Geology, 1985Field relations in the emergent part of the Makran accretionary prism show that a mid-Miocene to early Pliocene slope and shelf sedimentary sequence was deposited directly on abyssal-plain turbidites without any detectable stratigraphic or structural discordance.

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.

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.

Abstract Gas hydrates are classified as a major unconventional resource and assumed to be a future potential energy source. High pressures, low temperature stability conditions of the hydrates restrict their occurrence to the permafrost and deep sea regions (from the continental slop to the abyssal).

Drilling the Un Drillable: A Case Study of the Bela Well in Makran Accretionary Prism
SPE/IADC Middle East Drilling Technology Conference and Exhibition, 2021Abstract The Bela Well is situated on Makran accretionary prism with several active mud volcanoes that makes conventional drilling challenging due to the extremely high pore pressure i.e. in excess of 15,000 psi and a very narrow window between pore pressure and fracture pressure. This adverse condition was observed in the 9 offset wells

Sediment compaction and fluid migration in the Makran Accretionary Prism
Journal of Geophysical Research: Solid Earth, 1989The Makran continental margin in the Gulf of Oman forms the seaward extremity of an accretionary sediment prism which extends several hundred kilometers inland. A recently acquired multichannel seismic reflection profile shot across the margin imaged the structure of the prism in greater detail than was previously possible and allowed us to investigate

A tectonic pulse in the Makran accretionary prism recorded in Iranian coastal sediments
Journal of the Geological Society, 2003Many recent studies of syndeformational sediments in a wide range of tectonic environments have improved our understanding of the development of individual or regional deformation structures. Here, we report studies of growth strata that imply an unexpected tectonic history within part of the Makran accretionary prism, currently the largest on Earth ...
