Geochronological Atlas of Major Structural and Petrological Complexes of Russia: basic information resource for the domestic geological industry

Geochronological Atlas of Major Structural and Petrological Complexes of Russia is a continuously updated summary of determinations of the isotopic age of rocks, ores and minerals using U-Pb, Pb-Pb, Sm-Nd, Rb-Sr, Re-Os, K-Ar, Ar-Ar and other methods with geo-reference to mapped subdivisions of serial legends to the State Geological Maps-1000/3 and -200/2. The GIS resource contains results for the area of the Russian Federation obtained at the up-to-date analytical level at the VSEGEI Center of Isotope Research, as well as in other isotope laboratories, published in peer reviewed domestic and foreign periodicals since 2002. Geochronological data are accompanied by detailed petrological and geochemical information. For the convenience of references to specific datings, the resource is also structured according to the years of new geochronological data acquisition (at present, at least 500 per year) in the form of annual geochronological bulletins of VSEGEI (for 2013–2022). To date, the Atlas database contains about 9000 relevant datings, of which about 70 % were obtained at the VSEGEI Center of Isotope Research and about 30 % at isotope laboratories of the Russian Academy of Sciences, universities and foreign centers.
