“…The widespread Late Permian granodiorites and quartz diorites intrude into the Proterozoic–Early Palaeozoic strata with zircon U–Pb ages of 254–259 Ma (Xie, Zeng, Yang, et al, 2022). A Triassic granitic pluton is locally exposed in the southwestern part of the region, which emplaced at ~233 Ma (Xie et al., 2022a). The Early–Middle Jurassic granitoids are mainly found in the western part of the field, along with minor occurrences in the eastern part.…”

Revealing hydrothermal evolution from the early oxide to late carbonate stages for quartz-wolframite vein-type deposits is essential for understanding the ore-forming process. In this study, we choose the Baishitouwa tungsten polymetallic deposit located in the southern Great Xing'an Range tungsten belt as a case study, and present detailed deposit geology and in situ fluid inclusion (FI) analyses including microthermometry, laser Raman spectra, and LA-ICP-MS microanalysis to address this issue. Four stages of hydrothermal activity were identified: (1) quartz-wolframite (I),(2) quartz-wolframite (II)-pyrite-chalcopyrite, (3) quartz-polymetallic sulphides, and (4) quartz-carbonate. Four types of FIs were recognized: CO 2 -rich, CO 2 -bearing, liquid-rich, and brine inclusions. Microthermometric data showed that the homogenization temperatures and salinities from the early to late stages are 380-460 C,
