New Age Data on Granitoids of the Southeastern Voznesenka Terrane in Southern Primorye

This paper presents new isotopic, geochemical, and geochronological data on granitoids of the southeastern Voznesenka terrane of the Khanka block of the Amur paleocontinent. These granitoids are assumed to be a source of gold and tungsten mineralization in the host Late Paleozoic and Early Mesozoic strata and were initially considered to be of Late Cretaceous age. However, according to U-Pb isotopic data on zircons, their age is Middle Permian (~267 ± 3 Ma), which contradicts the idea of them being an ore-generating system that triggered the formation of mineralized zones in the associated younger volcanosedimentary and terrigenous formations of the Middle–Late Permian and Triassic age, respectively.
