Geological and Geochemical Study of Gold and Base Metals Mineralization in the Surupa Area, Borena Zone, Southern Ethiopia

Abstract

The paper reported the information on geology, alteration pattern, ore minerals and geochemical investigation for gold and base metals and to delineate potential area of gold and base metals mineralization. The results showed that the study area consists of heterogeneous sequences of medium to high-grade poly-deformed gneisses with igneous and sedimentary precursors and structurally affected by three phases of deformation (D1 to D3) like foliations, mesoscale folds, veins and fractures/joints respectively. The nickel and cobalt are highly anomalous elements indicating the source for the mineralization controlled by different structures such as fractures and joints. Pyrite, magnetite, goethite and hematite are ore mineral assemblages characterize the mineralization of the area.
