A tectonic pulse in the Makran accretionary prism recorded in Iranian coastal sediments

Journal of the Geological Society, 2003
Many 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 ...

Power‐Law Viscoelastic Flow of the Lower Accretionary Prism in the Makran Subduction Zone Following the 2013 Baluchistan Earthquake

Journal of Geophysical Research: Solid Earth, 2022
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.

Stratal Extension in Thrust Footwalls, Makran Accretionary Prism: Implications for Thrust Tectonics

AAPG Bulletin, 1986
ABSTRACT Small-scale stratal extension is commonly associated with thrust faults in the Makran accretionary prism of southwest Pakistan. Low-angle normal faults, dipping in the direction of transport relative to the thrust, are common in gouge zones and duplexes, and may also cut the footwall and hanging wall, where they cause stratal

Gas hydrates acting as cap rock to fluid discharge in the Makran accretionary prism?

Geological Society, London, Special Publications, 2002
Abstract We present a numerical model of the geothermal field of the Makran accretionary prism and of the slab being subducted below it. Calculated heat flow density values for the sea floor of the abyssal plain and the shelf slope are compared with in situ measured and bottom simulating reflector (BSR ...

Seismic quality factors across a bottom simulating reflector in the Makran Accretionary Prism, Arabian Sea

Marine and Petroleum Geology, 2011
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.

Offshore Frontal Part of the Makran Accretionary Prism: The Chamak Survey (Pakistan)

2007
The Makran accretionary prism developed in the north-western part of the Indian Ocean as a consequence of the subduction of the Arabian Sea since Late Cretaceous times. It extends from southern Iran to the Baluchistan region of Pakistan where it joins the Chaman-Ornach-Nal left-lateral strike-slip fault systems to the north and the Owen Fracture Zone ...

A preliminary study on geomorphological characteristics and genetic mechanism of pockmarks in the Makran accretionary prism, northern Arabian Sea

Geo-Marine Letters, 2021
Submarine pockmarks are residual negative geomorphologic features on the seafloor, which are generally considered to be related to fluid escape. In this paper, the geomorphological characteristics and genetic mechanism of pockmarks in the Makran accretionary prism are analyzed by using multi-beam bathymetric data and multichannel seismic data.

The brittle-ductile transition signature in accretionary prism, insight from thermomechanical modeling. Application to Makran

2022
<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.

Comparison of measured and BSR-derived heat flow values, Makran accretionary prism, Pakistan

Marine Geology, 2000
Abstract During the German research cruise SO-124 on RV Sonne (fall 1997) on the Makran accretionary wedge off Pakistan, geophysical investigations were carried out to study the thermal regime at a gas hydrate bearing sediment in a tectonically deformed accretionary wedge.
