The distribution of the main gold deposits in the history of the Earth is considered. Primary heterogeneity of the Archean crust by gold bearing is shown. The main gold ore metallogenic epochs are characterized. Links of gold deposits with VMS and Cu-Ni in the early periods of the Earth (Archaean-Proterozoic) and, in addition, with deposits of W, Mo, Cu, Sb, Hg and Sn in the Phanerozoic are shown. An analysis of the distribution of mineralogical and geochemical types of the actual Au mineralizat...

For the first time very low values (up to 0.706707) of the ratio 87Sr/86Sr were recorded in the biogenic carbonates of the Omolon massif (Northeast Asia) of the Capitanian age. These results are in good agreement with previously obtained data on limestones in Japan (Kani et al., 2013; 2018). In general, the strontium ratio curve constructed by us repeats the well-known world trend, differing by its somewhat underestimated (by an average of 0.0005–0.0008) values. The Capitanian strontium minimum ...

Based on the analysis of modern genetic models, an algorithm for extracting the derivatives of potentially ore-bearing magmas among Precambrian rocks of the tonalite-trondhjemite-granodiorite associations (TTGA) is developed and tested. The algorithm is implemented as a sequence of geochemical criteria to identify the genetic nature of the sources of substance and on this basis to distinguish the products of melting of geochemical reservoirs enriched in Au and other ore elements. The proposed al...

The composition and genesis of Pb–As–Sb sulfosalts from ores of the Berezitovoe gold deposit, Upper Amur Region, located in the eastern part of the Mongolia-Okhotsk orogenic belt are reported. Lead (Pb–Cu) sulfosalts are tsugaruite, dufrenoysite, boulangerite, menegenite, Bi-rich menegenite (Bi up to 11.5 wt %), and minerals of the jordanite-geocronite and bournonite-seligmannite solid solution series. Basic features of the relationship between Pb sulfosalts and ore and silicate minerals in vari...

The experience of LA—ICP determining of the isotopic composition of sulfur pyrite and arsenopyrite of gold deposits of the Baikal-patomsky plateau is considered. The technique is characterized. It is shown that all the studied samples have values δ 34 S and δ 33 S strictly corresponding to the law of mass-dependent fractionation of sulfur isotopes. A regular alleviation of the isotopic composition of sulfur of pyrite as its crystals grow for Sukhoi Log and the isotopic homogeneity of pyrite and ...
