Abstract

Study area is located in the eastern sector of Saharan Meta - Craton that includes the western part of Bayuda Terrane and extend southwest to Sodri - Um Badir shear zones. The sector is dominated by metasediments, metavolcanic - sedimentary series represented by chlorite - schist, quartzite, calc - silicate, and marble. Low - grade metamorphic arc - related volcano - sedimentary sequence occurs as thin narrow bands and subjected to tectono - thermal events of Pan - African orogeny during the Late - Proterozoic era (900 - 550 Ma). All these rock sequences have been intruded by syn to Late Orogenic Granitoids and post - orogenic ring - shaped complex and felsic dykes. The intrusions are thought to be the source of hydrothermal fluids that caused the precipitation of gold. Similar characteristics of geological features and tectonic settings support the possibility of the extension of gold mineralization between shear zones. The comparison between the three gold mineralizations reveals variations in minerals assemblages, pathfinders and gold grade. The result of this study defines a new metallogenic province in the west of the River Nile, which occupies a very large area covered by Phanerozoic sediments. Numerous mineral deposits of economic potentiality have been targeted along the shear zones and related fractures and faults. Among those potential deposits, five of them have been chosen as targets for future gold exploration and evaluation.
