STRUCTURAL AND GEOPHYSICAL STliDIES AROUND THE ABU RA\VASH DISTRICT, SOUTH\VEST CAIRO, NORTHERN EGYPT

Abstract

The Abu Rawash area is located to the southwest of• Cairo. and is geologically significant because of its surface exposure of l :ppn C'rctaeeous rocks . It can be used as a stratigraphic and structural mndcl fur the w'estern Desert .

atuan rocks

The exposed composite stratigraphic section includes L. Cemlm­ Turonian . Senonian , M & U Eocene , Oligocene and Quatemary whereas subsurface stratigraphic section includes Basement .

l'nleozoic. Jurassic . L. Cretaceous and L. Cenomanian .

The structure of the Abu Rawash area is complex ''ith frequent folding and faulting . The faults dissect different rock units of dirterent ages . They are classified mto three categories , nonnal . re,•erse. and wrench faults Both surface and subsurface data indicate . that llowcr structure are exist 111 the study area these structures arc commonly associated with wrench faulting . The study area. is als\l characterized by heterogeneous fold styles with different directions . The folds are plunging anticlines and synclines oriented in a NE direction except Tell El Mabsuta folds which plunge to the WNW . The E

trending folds are matching with Svrian Arc system of folds.
