 COMPARATIVE STUDY ON VARIOUS SULPHIDE RICH MINERALIZATIONS, NORTH KORDOFAN STATE, SUDAN

This study is essentially based on comparison between geochemical data of various mineralizations located at Kordofan province. Each of these ore deposits characterized by elements that radically different than the other, that include lithology, degree of metamorphism, categorized genetic model known, geochronology, and definitive geological environment. Precisely, three VHMS Gammama, Mazroub and Fuga ore bodies, SEDEX sulphides at Abu Zaema, Quartz veins and quartzites at El Firga and Tinna close to Mazroub.

These ore bodies imply huge surface area from Mazroub to the east to Um Badir to the west. Despite these diversified and intricate geological environments that embrace all these ore bodies, and based on chemical grounds a common signature was found. The only conceivable model to this common signature is attributed to magma chamber conditions and the associated hydrothermal solutions. The slight differences in chemical signal may be attributed to magma hiatus and impetus as all these mineralizations are products of rejuvenation and multiple episodes hydrothermal activities was the main mechanism of formation. These properties that make all these ore bodies carry sulpides that usually associated with precious metals rendered them as highly exceptional geological phenomena and above all particularly highly enriched terrane of highly economic value. Mineral exploration in such terranes is imperative and most of the time fruitful.
