SEISMIC OVERVIEW OF MAKRAN OFFSHORE

Abstract

The Makran accretionary prism developed has a kuge potential of kydrocarbons in form of gas consequence of tke subduction of tkekydrates in tke north-western part of tke Indian Ocean as a Arabian Sea since Late Cretaceous times. Tk Makran accretionary prism results from tke nortkward ic crust (Wkite and Klitgord, 1976; Wkite, 1983; Minskull et aL, 1992), with an average speed of 3 cm/year at present. Large kistoric eartkquakes, suck as tke magnitude 8.2 recorded in November 1945 (Packeco and Sykes, 1992; Byrne et aL, 1992), are clearly related to tke skallow dipping inter-plate mega-tkrust. Tkis subduction has caused a tremendous change in tke subsurface Fairly sizable sources and reserves are found. Tke complexity of tke structures is a barrier to the appropriation o/tke data collected.
