Gold–Palladium–Platinum Mineralization of Paleocene Explosive Structures, the Taukha Terrane, Sikhote-Alin

Noble-metal mineralization of the Paleocene explosive structures of the Taukha terrane in Sikhote-Alin is ascribed to the gold–palladium–platinum type. It occurs in igneous rocks, fluidolites, and rodingites. The mineralization is unusual in the presence of so-called “cupriferous gold” in association with minerals of Ni, Sb, and S, native elements, disordered solid solutions, and intermetallic compounds. In this respect, it has much in common with noble-metal mineralization in rodingites of some known occurrences. Native elements, disordered solid solutions, and intermetallic compounds of different metals, including noble metals, were formed in high- and ultrareducing conditions owing to the low to medium-temperature hydrothermal activity that accompanied the formation of Paleocene explosive structures of the Taukha terrane.
