Abstract : Detailed field mapping and structural study of J. Abu Ghurrab area indicate that the uppermost Precambrian sediments and volcanics of the Fatima Formation were deformed by NNW-SSE tangential compressian. The styles of deformation include flexural-slip folding forming a large, ENE to NE plunging, overturned syncline and low-angle thrusting in a hinterland dipping duplex. The floor thrust of the duplex is a decollement between the 150 metersthick andesite silLand the underlying limestone beds of the middle Fatima member. The roof thrust of the duplex has the largest displacement among the mapped thrusts. The duplex was formed qy continued shortening of the area as the thick andesite sill of the middle Fatima member acted as a rigid and brittle beam that resisted folding and failed by low-angle thrusting. Layer-parallel shortening by minor folding and thrusting is also common in the area and represents an early phase of deformation
