УДК 550.84 Spiridonov I.G. (IMGRE) imgre@imgre.ru IMGRE – 60 YEARS OF RESEARCH AND PRODUCTION The paper displays a 60-year retrospective of the research and productive activities of IMGRE. The Institute has been established for scientific support of inter-disciplinary studies of the national and foreign mineral deposits and mineral base of rare chemical elements. These objectives remain relevant up to this day. Besides, the Institute participates in the regional geological survey projects (i.e., in their geochemical parts) and methodologically supports the geochemical exploration projects, including peer reviewing of their results. Besides, IMGRE staff carries out various geoecological studies. Keywords: IMGRE, rare elements, mineral deposits, mineral base, mineralogy, geochemistry, ecology, mapping, geochemical methods, history. Р. 3-6 |

Regional geochemical cartography is not just a tool to reveal a hierarchy of geochemical fields but to establish their spatial correlation with lithologies and structures, determine their geochemical and metallogenical specialization, as well as general prospectivity. Keywords: geochemical cartography, geochemical methods, multi-purpose geochemical mapping, anomalous geochemical field, geoinformational model, geochemical specialization. Р. 6-13 |

(IMGRE) // imgre@imgre.ru GEOLOGICAL-GEOCHEMICAL MODEL OF THE STRUCTURAL-SUBSTANTIAL COMPLEXES OF THE CIRCUMPOLAR ARCTIC On the basis of morphostructural studies and correlation of geological-geophysical sequences of the key structural-substantial complexes underlying the Russian polar Arctic sector and circumpolar Arctic, a new geological-geochemical model of this segment of the crust; in compliance with it, its central element is a sub-latitudinal global trans-Arctic zone of the Paleozoic-Mesozoic plate cover in the continent-sea system (Eurasian Arctic coast – shelf, islands – the Arctic Ocean bathyal – North Canadian Arctic coast). The zone’s birthplace was a global-scale Neoproterozoic extension area developed in the Archean crust of the Arctic mega-craton; later within the central part of the area an inter-continental Arctic basin of the existing ocean evolved. Keywords: bathyal of the Arctic ocean, global trans-Arctic zone in the continent-sea system, Paleozoic sedimentary plate cover, geologic-geochemical model of the crust’s evolution. Р. 13-19 |

The drillhole-based subterranean leaching technique was developed with ammonium perrhenate as a commercial product. On the basis of the above, along with feasibility studies, the deposit’s mineral reserves were officially registered by the State Commission on Mineral Reserves (GKZ). Keywords: rhenium, coal resource potential of a basin, geochemical zoning, drillhole-based subterranean leaching technique, sorption, Briketno-Zheltukhinskoe mineral deposit. Р. 20-26 |

The model displays spatial distribution of the associations of elements and mineral assemblages and, being multilevel, it fully reproduces the stages of ore formation at the Peschanka. The indicator of vertical geochemical zoning AgPbZn/CuBiMo was recommended as it is of practical importance to assess erosion level of porphyry copper mineralization.

Vernadsky RAS) // yanin@geokhi.ru THE DEPORTMENT OF HEAVY METALS IN TECHNOGENIC SILTS OF THE RIVER Studied the levels of concentration and chemical states of heavy metals (Cd, Cu, Ni, Pb) in the background alluvium and in the technogenic river silts. It is established that metal concentrations in the silts by many times exceed their contents in the background alluvium. It is shown that in the technogenic silts sharply predominate the mobile forms of metals, especially sorption-carbonate forms. This defines the role of technogenic silts as the second source of the pollution of water mass and he indicates the possibility of their direct toxic action on the living organisms. Keywords: аlluvium, technogenic silts, heavy metals, speciation of metals, migration, mobility. Р. 54-59 |
