Abstract
The studied area occupies the northwestern comer of El-Zeit Range which lies along the western side of the Gulf of Suez. Both basement and the sedimentary sequence are well exposed exhibiting a series of elongated ridges running parallel to the Gulf of Suez. Gebel El-Zeit area represents an ideal example to the complex structure of the Gulf of Suez region. It has been strongly affected by rift faulting, related to ”circurnferontial tension” in the earth’s crust. The exposed structural elements at Gebel El-Zeit are represented by a complex arches at the major downthrown block eastward, and in a minor buried horst block westward. Thus the area provides an ideal models for the regional tectonics and structural relationships to sedimentary history of the Gulf of Suez area. Lithostratigraphically, Gebel El-Zeit area includes 10 district rock units (Allam, 1988). The Precambrian granite is unconformably overlain by the Cambrian clastic deposits representing the first marine transgression (Araba Formation), followed by alluvial plain, continental environment (Naqus Formation). After a substantial hiatus in sedimentation took place, a Cretaceous sequences (Malha, Galala, Wata and Matulla Formations) were lain down. The following Miocene marine transgression was accompanied by deposition of marine and non marine-coastal sediments (Nukhul, Ras El Bahar, Belayim and South Gharib-Zit Formations). It is believed that Gebel El-Zeit area was structurally high during that time and formed somewhat an island at the Gulf of Suez. Following this, a continued uplift tilted the beds to their present position. During the Pleistocene and Holocene times, the water of the Gulf of Suez advanced over the essentially stationary ranges, leaving sub-horizontal limestone terraces and perched beaches. The recent terrestrial deposits are primarily coarse clastic alluvial fans, while reefs continued to form off-shore.
