Wolframite is an uncommon mineral in epithermal gold deposits, but it has been reported in a number of cases including Baia Sprie, Romania (Ianovici and Borcos, 1982); Cirotan, Indonesia (Milési et al., 1994); El Indio, Chile (Siddeley and Araneda, 1986); Julcani, Peru (Deen et al., 1994), and Cripple Creek, Colorado (Bernstein, 1988).

 — In-situ U–Pb dating of wolframite from the Dongping deposit yields the age of 129.5 ± 4.8 Ma.. In-situ U–Pb dating of wolframite from the Dahutang deposit by LA-SF-ICP-MS yields the age of 137.3 ± 4.8 Ma.. Two significant quartz-wolframite veining events occurred at ∼130 Ma and ∼140 Ma in the Jiangnan W metallogenic belt.

 — The Baishitouwa deposit is a medium-scale quartz–wolframite vein-type deposit in the southern Great Xing'an Range tungsten (W) belt. The W mineralization occurs mainly as veins and dissemination within the mica schist of the Mesoproterozoic Baiyunebo Group. The formation of the deposit can be divided into four stages. The …

 — Except for several granite-related scheelite-quartz vein deposits such as the Yangjiashan deposit, South China (Xie et al., Li et al., 2021a, Li et al., 2021b), wolframite is the dominant ore mineral in granite-related W–Sn deposits. Wolframite has been proved to be stable over a wide range of temperatures and pressures (300–900 ℃ and 0.5 ...
