Ore genesis of the Narenwula quartz-vein type W polymetallic deposit in the southern Great Xing’an Range W belt, NE China: Constraints from wolframite geochronology and individual fluid inclusion analysis

Formation and evolution of multistage hydrothermal fluids in the Baishitouwa quartz–wolframite vein‐type deposit in the southern Great Xing'an Range tungsten belt, NE China: Constraints from individual fluid inclusion LA‐ICP‐MS analysis

“…More than 200 individual FIs from selected assemblages were measured by LA‐ICP‐MS to obtain their major and trace element compositions. The measurement was conducted using an Agilent 7900 ICP‐MS equipped with a Coherent GeoLas HD 193 nm ArF excimer laser at the Key Laboratory of Mineral Resources, IGGCAS following the procedure described in Xie, Zeng, Huang, et al (2022). The quartz samples were loaded and analysed in an in‐house rhomb‐shaped plexiglass cell of relatively small internal volume.…”

“…Subsequently, this technique has been widely applied in hydrothermal deposits to provide new perspectives on the composition and evolution of ore‐forming fluids and metal precipitation mechanisms (e.g., Chen et al, 2021; Shu et al, 2017; Shu et al, 2021). In recent years, this method has been successfully applied to hydrothermal W deposits and proved to be an effective method of tracing the delicate fluid evolution and mineral precipitation processes, such as the Panasqueira W deposit in Portugal (Lecumberri‐Sanchez et al, 2017), the Zinnwald Sn–W district in Germany and Czech (Korges et al, 2018), the Maoping W–Sn deposit, the Piaotang W–Sn deposit (Legros et al, 2019; Yang et al, 2019), the Yaogangxian W deposit (Pan et al, 2019), the Chuankou W deposit (Li et al, 2022), and the Tiantangshan Rb–Sn–W deposit (Peng et al, 2022) in South China, the Jiaoxi W deposit in the Lhasa terrane (Wang, Tang, et al, 2021), and the Narenwula W polymetallic deposit in NE China (Xie, Zeng, Huang, et al, 2022). In addition, scanning electron microscopy‐cathodoluminescence (SEM‐CL) is considered as a useful analytical approach to identify different generations of quartz, expose microstructures such as growth zoning and deformation features, and reconstruct quartz formation and mineralization history (e.g., Haroldson et al, 2020; Pan et al, 2019; Rottier et al, 2021).…”
