U-Pb Dating, Lead Isotopes, and Trace Element Composition of Pyrite Hosted in Black Shale and Magmatic Rocks, Malaysia: Implications for Orogenic Gold Mineralization and Exploration

Several orogenic/sediment-hosted gold deposits are widely distributed in the Central Belt of Peninsular Malaysia. This study combines U-Pb dating with isotope composition lead as well content ore and magmatic rock-hosted pyrite. It aims to investigate age mineralization possibly establish a link between intrusion district. The results show that S-type rocks yield crystallisation ages ranging from 204.1 ± 4.7 Ma 223 3.2 low magnetic susceptibility measurements below 3 × 10−3 SI unit. These fit within 200–250 Pb-Pb model Pb isotopic K-feldspars. Pyrite trace element mapping has shown zoning patterns occurring at same time cores pyrite grains indicate approximate is 200 Ma. close 197–199 (Early Jurassic), previously determined by K-Ar sericite which was interpreted be mineralization. In this study, varies up 793 ppb analysed pyrites, indicative likely contribution
