Аннотация
The mineral composition and geochemical characteristics of the ores of the Malinovskoe gold-ore deposit are studied by the data from mining works (ditches, cleanings, and boreholes). It is found that the ore–magma system of the deposit was formed in several stages of mineralization characterized by two phases of magmatism differing in age. In terms of the set of features (the geological–structural position of the deposit, as well as the material composition and geochemical characteristics of the ores), the deposit is attributed to the gold–tourmaline type of mineralization associated spatially and genetically with the “raremetal” granitoid magmatism. This type has not previously been found in Primorskii Krai. The studies of the material composition and geochemical characteristics of the ores allow us to ascertain the correlations between the elements along with the reasons of their origination. By analogy with other gold-ore formations of the Russian Far East, the mineralogical and geochemical model of the deposit is developed (Be–Sn–Cr–Ba–Au–Cu–Mo–Pb–V–Ti–Co–W–Ag–Bi–Ni–Mn–Sr–Zn–Sb–As modeling element series of vertical zoning), which enables us to estimate the levels of the erosion section of the ore bodies and to evaluate their prospects. It is found that the most productive associations in the deposit are the gold–bismuth geochemical association (Au–Ag–Bi–Cu–As–Co) and, to a lesser degree, the gold–tungsten association (W–Au–Ag–Cu–Bi–As).
