Paleoproterozoic age of the Zeya Group, Stanovoy Complex of the Dzhugdzhur-Stanovoy Superterrane (Central Asian mobile belt): Results of Sm-Nd isotopic and U-Th-Pb geochronological (LA-ICP-MS) D degrees nalyses

摘要

Geochemical Sm-Nd isotope and U-Th-Pb geochronological (LA-ICP-MS) studies have demonstrated that the Zeya Group of the Stanovoy Complex of the Dzhugdzhur-Stanovoy Superterrane (Central Asian fold belt) is not Paleoarchean, as was previously thought, but Paleoproterozoic in age.
