Geological Evolution of Sukari Gold Mines Area- Eastern Desert, Egypt

Abstract

Many common mineralized localities in the Eastern Desert of Egypt (E.D.E) are now announced as mineralized occurrences or as ore deposits for various ore minerals.The Sukari gold mines area is now worldwide famous explored and exploited site for gold as major product .In addition, other economic minerals such as; Ag, Cu, Pb, Sn, Mo, and others are important minerals association to be considered. Different basement rocks hosting mineralization in Sukari gold mines area were studied ,such as; metavolcanics and related volcanoclastics, metasediments, granite porphyry, mafic and ultramafic rocks they have been exposed showing rugged topography characterizing the study area where those within the granites are the most important. These rocks have been subjected to a number of tectonic and structural events, Also stockwork quartz veins and veinlets and quartz ridges cutting across the basement rocks. Besides, alteration processes are commonly observed in the Basement rocks of the study area.The Sukari gold mines area is now considered as one of the most important gold productive mines on the world scale. This study provides an update geological, structural and petrographical tries to assist in understanding the mode(s) of formation of the mineral potentiality of the Sukari gold mines study area and surroundings. Based on the field works and lab data results, it is recommended that in the Sukari gold mines area, the gold amounts increase with depth and westward.

“…1 , unfolds against the backdrop of the Arabian-Nubian Shield, a formation dating back 900-650 million years. The rock sequence at Sukari, an integral part of this shield, comprises calc-alkaline igneous rocks and metal sediments [ 30 ]. The Um Khariga Metapyroclastics, situated west of the Sukari granitoid and surrounding serpentinite, and the Sukari Metavolcanics are separated by this district-scale system, extending 25 km and passing immediately to the east of Sukari.…”
