Abstract

Selinsing Gold Mine, Pahang is an active mining area. The underlying lithology is dominated by sedimentary rocks (shale, mudstone, siltstone, limestone) and volcanic rocks (tuffaceous siltstone/shale, lithic tuff to tuffaceous sandstone) which have undergone low grade metamorphism. The rocks belong to the Gua Musang Formation of Late Permo-Triassic age. The gold mineralisation occurs in quartz veins and wall rocks with intensive alteration that are related to the N-S and NE-SW lateral faults and shear zones. Common minerals associated with gold are pyrite, arsenopyrite, chalcopyrite, tetrahedrite and sphalerite. Traces of scheelite, goethite, carbonate, carbon and muscovite are also observed. Field studies indicate that in addition to the development of quartz veins system, the rocks have also been folded and experienced lateral or reverse faulting. Based on the relationship of the structures, two phases of deformation were determined. The first deformation generation occured during the Triassic, resulted by a compression from east-southeast, which produced the main folds. The late phase of the first deformation also resulted in the formation of reverse faults, NS dextral lateral faults and refolded folds associated with reverse faults and quartz veins. Second deformation was resulted from east-west compression system, forming lateral shear zones and quartz veins. Formation of quartz veins are mainly related to the right lateral faults.
