Shkodzinckiy, 2014). These data and the analysis of the geochemical maps of the Russian Arctic polar sector compiled for the first time from the floor sediments and the rocks of the Arctic Ocean floor and the coast suggest that all structural-matter complexes of different age of the area under investigation developed on the crust of continental type. Continuous transition is shown of complexes of East European platform into Barents – Kara basin and complexes of Yana-Chukotka-Alaska region into Amerasian basin of the Arctic Ocean ,where Lomonosov Ridge and Mendeleev Rise are natural continuation of the continental part of Eurasia.

(IMGRE) // firstname.lastname@example.org GEOCHEMICAL CRITERIA FOR LOCATING HIGH-RESOURCE OIL AND GAS AREAS IN REGIONAL WORKS The distribution is studied of anomalous fields of adsorbed hydrocarbon gases and superimposed haloes of microelements in soils of oil and gas bearing areas. On the basis of revealed geochemical criteria, the technology to locate areas promising for finding large deposits of oil and gas was developed. The possibility of finding potential high-resource oil and gas bearing areas was substantiated in traditional regions of oil and gas extraction in the European areas of Russia.

(IMGRE) // firstname.lastname@example.org PROBLEMS OF VOLCANIC COMPLEXES GEOCHEMICAL SPECIALIZATION IN CONNECTION WITH REFERENCE GEODYNAMIC SETTINGS In addition to the lithophile, chalcophile and siderophile specialization it is offered to put into practice of regional geochemical work the factors of geodynamic, alkaline, ultramagnesian, potassic, agpaitic and plumasite specialization. Influence of these factors on trace elements concentrations, appreciation of background contents, interpretation of anomalous geochemical fields, diagnostic criteria of tectonic (geodynamic) environments becomes obvious. The possible varieties and grades of geochemical specialization categories, examples of positive and negative effects of these factors on the LILE, HFSE, REE, radioactive, siderophile and chalcophile elements are considered.
