Petrographic investigation and geochemical survey of rocks in Inteet area (Nile River State, Sudan)

The aim of the work is to estimate the Inteet area for search for gold mineralization. This area is located between Umm Trambishi and Alsalam area in Nile River State, Sudan. Surrounding territory is a gold-mining region, in which there are known deposits with estimated resources, as well as promising places where local prospecting is carried out. For a preliminary assessment of the prospects of the site is necessary to conduct geological and geochemical studies. Evaluation of the geological environment was carried out both during field work and with a petrographic microscope. 11 thin sections of rock samples have been prepared and petrographically investigated under polarized microscope the mineral compositions, textures, microstructures, degree of alteration and metamorphism have been studied. Geochemical studies were conducted on 32 samples from 25 sampling points. The main results of petrographic investigation and geochemical survey show the presence of hydrothermal alteration zones, which are associated with a high content of elements-indicators of gold mineralization. In general, the territory can be assessed as promising, but requiring further exploration and assessment work. © Published under licence by IOP Publishing Ltd.
