Abstract
Selinsing Gold Mine is an active gold mine located in northwest Pahang, Peninsular Malaysia. Lithology of the area consists of low-grade metamorphosed sedimentary and volcanic rocks of Gua Musang Formation of Late Permo-Triassic age. The gold mineralisation occurs in quartz veins that cut host rocks and are related to the N-S and NE-SW lateral faults and shear zones in the area. Minerals associated with gold are pyrite, arsenopyrite and traces of chalcopyrite, tetrahedrite and sphalerite. Wall rock alteration in Selinsing Gold Mine shows a direct relation with hydrothermal solution, structures, formation of quartz veins and gold mineralisation. Wall rock alterations related to mineralization are recognized from combined data from field observations, mineral alteration and trend of chemical compositions. They are silicification, sericitization and argilitization. Silicification is marked by the presence of secondary quartz and sericite, are is characterized by a decrease in K2O, Al2O3, LOI, Fe2O3 and increase of SiO2, Na2O. Argillic alteration is indicated by the development of clay minerals such as kaolinite, muscovite and quartz, accompanied by an increase in K2O, Al2O3, LOI, and a decrease in SiO2. Sericitization is characterized by the formation of sericite, clay minerals, quartz, chlorite, carbon, sulphides and minute traces of gold. This alteration is characterized by an increase of K2O, Al2O3, LOI, Fe2O3 and Mg, loss of Na2O and abrupt losses of SiO2.
