Offshore Frontal Part of the Makran Accretionary Prism: The Chamak Survey (Pakistan)
, 2007The 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 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 ...

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 ...

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.

We report the first discovery and sampling of a methane-hydrogen sulfide rich “cold seep” from the Makran accretionary prism off Pakistan (Arabian Sea). A variety of cm- to m-scale pockmarks and gas seepage structures were identified from underwater TV-photo sled profiles crossing the oxygen minimum zone (OMZ), related to highresolution seismic ...

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 ...

Abstract The Bajgan Complex, one of the basement constituents of the arc massif in Iranian Makran forms a rugged, deeply incised terrain. The complex consists of pelitic schists with minor psammitic and basic schists, calc silicate rocks, amphibolites, marbles, metavolcanosediments, mafic and felsic intrusives as well as ultramafic rocks. Metapelitic
