Abstract

The northern Sinai inverted basins exhibit superb outcrop examples of compressional transfer zones and display the control of these zones on syntectonic and post-tectonic sedimentation. Two main types of transfer zones, hard- and soft-linkage transfer zones, were identified at different scales. Hard-linkage transfer zones form inward and outward fault kinks whereas the soft-linkage transfer zones are expressed by plunging anticline–syncline pairs between overlapping positively inverted fault segments. An example of a wrench-related compressional transfer zone is also displayed by a restraining-bend anticline formed within the strike-slip fault system of the Sinai hinge belt. The displayed examples of compressional transfer zones invariably exerted fundamental control on deposition of syn- and post-tectonic sediments, flow directions of drainage systems, locations of sediment entry points, and the intensity of erosion patterns of the structurally high sediment source areas. This study highlights the close relationship between the transfer zones and hydrocarbon accumulations in clastic syntectonic reservoirs in inverted and wrench basins.
