Crustal and Mantle Sources of Lead in W-cu-sn Ores of the Badzhal-komsomolsk Metallogenic Zone of the Sikhote-alin

Year: 2025

Type: article

Abstract: The Pb isotope composition of W-Cu-Sn ores of the Festivalnoe and Pravourmiyskoe deposits, flyschoid rocks of the Badzhal terrane and ore-bearing granitoids from the Badzhal and Silinka complexes of the Badzhal-Komsomolsk metallogenic zone of the Sikhote-Alin was studied based on the high precision analysis data. These data and the Sr-Sm-Nd analysis results suggest that the ore-magmatic systems of the Badzhal and Komsomolsk ore districts formed as the result of the mantle-crust interaction during the Albian-Cenomanian orogenesis. Based on all the research results and taking into account the abnormal Sn content of the flyschoid rocks and ore-bearing granitoids, the authors assume that a granite-metamorphic layer of the young continental crust, resulting from orogenesis, should be regarded as the ore-geochemical reservoir of the Badzhal-Komsomolsk metallogenic zone.
