Özet:

The areas of study constitute the eastern sector of Saharan Meta-Craton which includes the western part of Bayuda Terrane and extend southwest to Sodri-Um Badir Shear Zones. The sector is dominated by metasediments, metavolcano-sedimentry series represented by chlorite schist, quartzite, calk-silicate and marble. Low- grade arc volcano-sedimentary sequence occurs as thin narrow bands and subjected to tectono-thermal events of Pan- African orogeny during Late-Proterozoic era (900 – 550 Ma.). All these rock sequences have been intruded by Syn-late orogenic granitoids and later by post-orogenic ring complex and felsic dykes. Those intrusions are thought to be the source of hydrothermal solutions that resulted in gold mineralization. Similar characteristics in geological, structures and geotectonic settings support the possibility of the extensions of gold mineralization between these shear zones. The comparison between the three gold mineralization zones revealsvariations in minerals association, pathfinders, and grade of gold content. The result of this study define a new metallogenic province in the region west of the River Nile, which occupy a very large area covered by Phanerozoic sediments. Numerous mineral deposits of economic potentiality have been targeted along those shear zones and their fractures and faults. Among those potential deposits, five have been selected as targets for future gold exploration and evaluation.
