The geology of the study area is constituted by feldspar quartz sericite schist,rnmuscovite chlorite schist , basic metavolcanics and granodiorite. The feldspar quartzrnsericite schist consists of thin intercalations of strongly silicified and chlorite talcrnschist . Additionally, granitic dykes and carbonate veins occur in this rock parallel tornthe regional foliation . The muscovite chlorite schist also has intercalations of quartzrnchlorite schist along its western margin. Major and minor quartz veins also occur inrnall major rocks. Foliations generally strike to the northeast and dip at moderate tornsteep angles to the west. Other geological structures evident in the study area includernfractures and small tight folds. These folds may represent the earliest phase folds inrnthe area .rnThe rocks are strongly affected by hydrothermal alterations. Wall rock alterationrntypes evident in the area include sericitization, silicification, carbonatization,rnchloritization, epidotization and sulfidation .rnGold mineralization might have resulted from hydrothermal processes that causedrnthe wall rock alterations. Open spaces along host rock fractures and foliations mightrnhave provided channel ways for the hydrothermal fluid. Gold has been detected inrnquartz and carbonate veins and altered feldspar quartz sericite schist, muscoviternchlorite schist . The highest gold content has been obtained in chlorite talc schist thatrnis intercalated in feldspar quartz sericite schist .Gold shows a slight positive correlation with cobalt. Though this result is notrnsufficient to suggest the source of the gold to be mafic- ultramafic rocks, it attractsrnattention for further studies in this regard .rnSome evidences from the granodiorite reveal that it is unlikely that the hydrothermalrnfluid emanated from this intrusive body.
