| Abstract | ||
| The area under study covers about 50 km2. and is located between Long.33o 19.3/ & 33o 24/ and Lat. 29o 1.5/ & 29o 5.3/. The present study is considered as an attempt to collect and integrate the previous shallow seismic refraction studies, to follow the Um Bogma mineralized Formation. This formation has physical parameters vary from the other rock-units, specially the amplitude of the velocity of seismic waves. Besides that, the study deals with the depth and thickness as well as the determination of the top and bottom of the Um Bogma Formation. There are four studies have been done in the area under investigation started by Talet Seliem area, Wadi Nasib area, Dabit El Qerie area and finally by Wadi El Seieh area. The results show vertically five seismic velocities related to five rock-units started at the surface by wadi deposits (500 m/s), compacted sandstone deposits (upper part of Abu Thora Formation) with seismic velocity varying between 1300 &1800 m/s, lower part of Abu Thora Formation (2000 to 2500 m/s) at wadi El Seih, while Um Bogma Formation (3200–3300m/s) at wadi Haseib area and finally the Adadia Formation with the highest seismic velocity (about 4700 m/s) related to wadi Seih area | ||
