Abstract Scheelite mineralization accompanied by traces of chalcopyrite occurs in skarn systems in the giant Zhuxi deposit in the Taqian area, Northeastern Jiangxi province, South China. Three paragenetic stages of skarn with ore deposition have been recognized: the prograde skarn, retrograde skarn and hydrothermal quartz-sulfide stages. Microthermometer data showed that the prograde skarn were formed at relatively high temperatures (450–>500 °C) and pressures (0.97–1.38 kbars) and low oxidation...

The Zhuxi W (Cu) skarn deposit is the largest W deposit in the Jiangnan porphyry–skarn tungsten belt in South China, and is also among the largest deposit of this type in the world. Titanite is a common mineral in the Zhuxi deposit, and occurs in three textural settings: titanite I associated with retrograde-altered exoskarn with weak mineralization; titanite II in retrograde-altered endoskarn with disseminated Cu ore; and titanite III from altered granite with disseminated W ore. Here, we prese...

Abstract A quartz-free scheelite-bearing fine- to medium-grained anorthosite occurs as a dike in the world-class Zhuxi scheelite skarn deposit of South China. The anorthosite mainly comprises An-rich plagioclase (Anavg = 91, ~90 vol%) + scheelite (~3 vol%) + apatite (~2.5 vol%) + ilmenite (~1.5 vol%) + titanite (~1 vol%), as well as minor (~2 vol%) fluorite, prehnite, chalcopyrite, pyrrhotite, pyrite, sphalerite, rutile, and uraninite. This paper reports the first occurrence of scheelite-bearing...

Abstract The Zhuxi W-Cu deposit, located in the Jiangnan porphyry-skarn W belt, is a world-class W deposit. We studied three coeval mineralization-related intrusions composed of biotite monzogranite, fine-grained granite, and granite porphyry in the Zhuxi mine. These rocks contain peritectic garnet and K-feldspar. The LA-ICP-MS U–Pb dating of zircon from the biotite monzogranite, fine-grained granite, and granite porphyry yields average ages of 149.38 ± 0.86 Ma, 149.0 ± 1.0 Ma, and 148.30 ± 1.4 ...

Abstract The giant Zhuxi tungsten deposit is located in the Taqian-Fuchun Ore Belt in northeastern Jiangxi province, and genetically associated with the Zhuxi granitic stocks and dykes. Three mineralization-related granites including granite porphyry dykes (GP), biotite granitic stocks (BG), and white granitic dykes (WG), were identified in the Zhuxi deposit. SHRIMP zircon U–Pb analysis for the three granitic rocks present ages ranging from 153.5 ± 1.0 Ma to 150.4 ± 1.0 Ma. The BG mainly contain...
