Abstract
Air Piau gold deposit represents a significant example of gold mineralization hosted within quartz veins formed by hydrothermal processes in Peninsular Malaysia. To better understand the genesis of these gold-bearing quartz veins and information future exploration tactics, this study examines the geochemistry and their rare earth element (REE) content that linked to them. Following extensive field sampling of quartz veins and nearby wall rocks, X-ray fluorescence (XRF) and inductively coupled plasma mass spectrometry (ICP-MS) were used for laboratory analysis. The existence of sulphide minerals like pyrite and arsenopyrite is indicated by the XRF data, which show that the quartz veins are mostly made of high-purity silica with varying iron and sulphur enrichments. A structurally controlled hydrothermal origin with well-developed geochemical halos extending into the surrounding host rocks is suggested by the high correlation between gold values and elevated quantities of arsenic and antimony, as confirmed by ICP-MS analysis. Results indicate that Air Piau’s metamorphic host rock was composed was mostly made up of greenschist, with various amounts of albite, epidote, and staurolite minerals present (greenschist was transformed into amphibolite facies) and it was distorted as a fault. The combined geochemical signatures and dispersion trends provide valuable insights for delineating prospective zones within the Air Piau area and support the development of more effective exploration models for similar gold deposits in the region.
