Abstract

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.

锡科特-阿林Taukha Terrane的古新世爆炸构造金-钯-铂矿化

摘要

Sikhote-Alin的Taukha地貌的古新世爆炸结构的贵金属矿化归因于金-钯-铂类型。它发生在火成岩，流纹岩和碳棒岩中。在与镍，锑和硫的矿物质，天然元素，无序固溶体和金属间化合物结合存在的所谓“铜矿”中，矿化是不寻常的。在这方面，它与某些已知事件的镁锰矿中的贵金属矿化有很多共同点。由于伴随着Taukha地层的古新世爆炸结构的形成，中高温热液活动在高还原和超还原条件下形成了包括贵金属在内的不同金属的本机元素，无序固溶体和金属间化合物。
