The Cretaceous Luk Ulo Complex (LUC) in Central Java, Indonesia, hosts orogenic gold-type ores with S derived from metapelite. host rock consists of accreted metapelite, metamorphosed under temperature up to 510 ± 30 °C. We investigated the textural and chemical evolution pyrite carbonaceous matter (CM), analyzed phases for trace elements (TEs) such as As, Pb, Cu, Sb, Te, Ag, Zn, Bi, Se, Hg, Au, aim documenting behavior these during prograde metamorphism evaluate implications on gold...
Abstract The Luk Ulo Metamorphic Complex, Central Java is a product of the Cretaceous subduction and accretion, includes diverse types protoliths. Two‐types primary mineralization have been recognized in this area, namely, (1) seafloor basalt‐hosted massive sulfide (2) low‐grade metamorphic rocks‐hosted vein type mineralization. Later erosion these formed placer gold deposits along rivers. However, source has never identified. Thus, study aims at understanding gold, characteristics...
