| Abstract | ||||
| The present work discusses the geological, petrographical and geochemical features of the metasediments in Wadi Zabarah area. Detailed field studies revealed that this area comprises two main rock types of the metasediments: 1) psammitic and psammopelitic schists and 2) cataclastic rocks. The psammitic and psammopelitic schists are classified according to grade of metamorphism into: tremolite-actinolite schists, graphite schists, tourmaline-bearing schists, beryl-bearing schists, quartzitic schists and garnet-bearing schists. Cataclastic rocks comprise protomylonitic, blastomylonitic and ultramylonitic schists. The geochemical characters of these rocks revealed that they are comparable with the non-peralkaline, peraluminous, continental and/or oceanic island arc sandstones. | ||||
