Program of systematic isotope, geochemical, and geochronological studies of geological complexes in Russia: Methods and initial results of 2022–2024

Karpinsky Institute launched a Rosnedra-driven long-term program for the systematic geochronological, isotope, and geochemical study of geological complexes in Russia in order to mainstream modern laboratory and analytical data in geological exploration. The program involves isotope dating, studying the petrographic, petrogeochemical, isotope, and geochemical compositions of igneous, metamorphic, and sedimentary rocks. The first stage of 2022–2024 covered dating as well as a set of analytical studies in 500 base stations in fold-belt regions of Russia. The obtained findings contribute to promptly specifying regional correlation diagrams for magmatism and metamorphism, creating new geological maps, and updating current ones; they frequently led to significant progress in reconstructing the metallogenic evolution and geological history of regional development. The geochronological results of studying the intrusive rocks of the Kuznetsk Alatau and greenschist complex of the Western Sayan in the Altai-Sayan Fold Area serve as an example. The Passports finalize the work by summarizing the results of petrological, isotope, geochemical, and geochronological studies for each explored object in the program. The Supplementary Data section contains examples of Passports for intrusive, metamorphic, and sedimentary complexes.
