The Gabal* Meatiq area was studied geologically and petrographically in detail by several workers. The present study aims at the delineation of the tectonic pattern of this area. Two major tectonic cycles affected the area, these are: the Early Proterozoic, characterized by the deposition of pelitic, calcpelitic and arenaceous sediments accompanied by the eruption of some volcanics. These formations were metamorphosed, migmatized and granitized to the amphibolite facies. Such conditions prevailed in the Protoplatforms, relicts of which are now preserved as Median Masses. The second tectonic cycle predominated during the Late Proterozoic during which an euogeosyncline developed. The tectonic evolution of this euogeosyncline included two stages. The Typical Geosyncline stage, which according to the rock types formed and the tectonic movements affecting them can be differentiated into three phases. The second stage is the Orogeni c Epigeosyncline , which again includes two tectonic phases. The orogenic epigeosynclinal stage continued during the lower Palaeozoic as evidenced by the presence of conglomeratic bands unconformably overlying the red-biotite granites of Um Had at Wadi** Umm Hassa. These conglomerates are believed to be Lower Palaeozoic in age.
