Abstrak

This study aims to identify geochemical and mineralogical anomalies within the Tantan Granite Formation at the Teluk Tilan site (Sample TL) in Merangin Geopark, Jambi, to understand the potential for metal enrichment. Petrographic, mineragraphic, and X-Ray Fluorescence (XRF) analyses were conducted on a granitoid sample from this specific location. Geochemically, Sample TL is classified as a Peraluminous (S-type) Granite, characterized by a molar A/CNK value of 1.282. This finding is considered anomalous because the rock exhibits the presence of Copper (Cu) mineralization with a concentration 0.1%. Mineragraphic analysis confirmed an association of metallic minerals, including chalcopyrite (CuFeS2), pyrite (FeS2), and most significantly, the presence of the secondary minerals Covellite (CuS) and Goethite (FeO(OH)). The occurrence of covellite indicates that this granitoid has undergone a post-magmatic supergene alteration process. This supergene process (weathering) triggers the leaching of primary copper and the re-precipitation of secondary copper, potentially leading to higher grades. The results support the interpretation that the Tantan Granite Formation records a complex magmatic evolution and holds indicators of a prospective base metal mineralization system within the Merangin Geopark area.
