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 ...

Reflection Termination Patterns in Piggyback Basins of the Makran Accretionary Prism
69th EAGE Conference and Exhibition incorporating SPE EUROPEC 2007, 2007P244 Reflection Termination Patterns in Piggyback Basins of the Makran Accretionary Prism R.A. Castilla* (IFP) N. Ellouz (IFP) & J.P. Brun (Geosciences Rennes Universite de Rennes 1) SUMMARY Thrusts activation and time span of activity is of capital importance for the history of fluid flow in thrust belts and accretionary prisms.

Stratal Extension in Thrust Footwalls, Makran Accretionary Prism: Implications for Thrust Tectonics
AAPG Bulletin, 1986ABSTRACT 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, 2002Abstract 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 ...

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.

Comparison of measured and BSR-derived heat flow values, Makran accretionary prism, Pakistan
Marine Geology, 2000Abstract 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.

This paper discusses the geodynamic evolution of the Makran accretionary prism from a new field investigation in the Pakistani area and from the interpretation of reprocessed seismic lines in the offshore area. The field reconnaissance has provided new structural data about the general structure of the prism and a rejuvenated stratigraphic chart based ...

Deformation of the Makran accretionary sediment prism in the Gulf of Oman (north-west Indian Ocean)
Geological Society, London, Special Publications, 1982Summary The offshore Makran of Pakistan and Iran in the Gulf of Oman forms the seaward margin of a folded and faulted accretionary sediment wedge which extends several hundred kilometres inland across the onshore Makran. Sediment is being scraped off the oceanic Arabian plate as it subducts shallowly northward beneath the Eurasian plate.
