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) аnalyses

Abstract

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.
