详细
The Taukha terrane of the Sikhote-Alin hosts outcrops of rocks with unusual structural and textural features, the compositions of which vary from ultrabasic to intermediate and from subalkaline to alkaline. These are hornblendites, mica–feldspar, amphibole–feldspar, and carbonatite-like rocks of vent facies, a dike of phlogopite–olivine rocks, and a small intrusion of melanocratic amphibole gabbro. The magmatic rocks, together with fluidolites and rodingites, compose explosive structures of Paleocene age. Rodingites were formed via the development of explosive structures resulting from metasomatic replacement of basic vent-facies rocks and small intrusive bodies in sedimentary rocks. The Paleocene explosive structures of the Mokrushinskaya and Shirokopadninskaya areas of the Olginsky ore district and breaking of Triassic carbonaceous silicites are genetically related to Au–Pd–Pt mineralization, the specific features of which are “cupriferous gold” (including the Zn- and Ni-bearing varieties of cuproauride and auricupride), native elements, and intermetallic compounds.
