Abstract
Based on the results of Sm–Nd isotopic geochemical and U–Th–Pb geochronological LA–ICP–MS studies, it has been established that the formation of metamorphic rock protoliths of the Stanovoi Complex in the western Dzhugdzhur–Stanovoi Superterrane of the Central Asian Foldbelt took place over the following time spans: 2750–2860 Ma (Ilikan Group of the Ilikan Zone), 1890–1910 Ma (Bryanta Group of the Bryanta Zone), and ~2.0 Ga (Kupuri and Zeya groups of the Kupuri and Zeya zones, respectively). It has been shown that the western part of the Dzhugdzhur–Stanovoi Superterrane was formed ~1.9 Ga ago, as a result of collision of the Neoarchean Ilikan Terrane, the Paleoproterozoic island arc, and the Paleoproterozoic Kupuri–Zeya Terrane. The data make it possible to consider the Kurul’ta, and Zverevo blocks of the Stanovoi Structural Suture and the Ilikan Terrane of the Dzhugdzhur–Stanovoi Superterrane of the Central Asian Foldbelt as constituents of a common terrane.
