| Abstract | ||
| Metavolcanic, metagabbro-diorite, granodiorite, Dokhan volcanic, monzogranite, and alkali feldspar granite rocks covered Dara area. In contrast, metagabbro-diorite, Dokhan volcanic and monzogranite rocks covered Um Balad area. The North Eastern Desert is dominated by tectonic faults and related joint sets system; the dominant trends are NE - SW and NW - SE structural trends. The Dara area was affected by the extensional deformation phases trending NNW - SSE, NW - SE, NE - SW, and NNE - SSW. While the Um Balad area is affected by extensional deformation phases trending NW - SE, NNW - SSE, and NE - SW directions. On the other hand, the Dara area is affected by the compressional deformation phases trending NE - SW, WNW - ESE, and ENE - WSW directions. Um Balad area is affected by compressional deformation phases trending WNW - ESE, NE - SW, and NNW - SSE directions. Mineralized tension joints are widely distributed with different trends in the study areas. Generally, the monzogranite is highly deformed rather than the metagabbro-diorite rocks in the Dara area. While the metagabbro- diorite rocks are the highly deformed rock type in the Um Balad area. | ||
