GOLD MINERALISATION IN RED SEA HILLS REGION, APART OF SAHARA DESERT, NORTHEAST SUDAN

摘要

In Sudan gold occurrences are mainly concentrated in Red Sea Hills region. Northeastern part of the country. Most of the gold occurrences in this region were superficially exploited in Pharaonic times as evidenced by old workings & numerous millstones. The gold mineralization in different parts of Red Sea Hills region are mainly associated with quartz veins & alteration zones confined within metavolcanics & meta-sedimentary rocks of Proterozoic age. These rocks have been subjected to low grade greenschist facies metamorphism. The gossan type deposit is characterised by a carbonate sedimentary complex intersected by gabbroic bodies. The gossan has been affected by regional metamorphism. The gold mineralization is intimately associated with ferruginous facies.
