Porphyry-type tungsten (W) deposits are of significant economic importance; however, their enrichment and precipitation mechanisms are still unclear. We studied the Yangchuling, South China, W-Mo deposit to uncover the ore-forming processes and metal enrichment mechanisms using scheelite geochemistry. Scheelite is the primary tungsten ore mineral i...

Discovery of the Jinshui skarn-type tin deposit marked the first instance of a tin deposit to be uncovered in the central segment of the East Kunlun Orogenic Belt (EKOB) in northwestern China.

The amount of melt extracted from a metasedimentary source is a major parameter in quantitative models of crustal processes; however, quantification of melt volume is thwarted by the heterogeneity of the crust and a lack of estimates concerning the amount of fluid present. We observe that highly systematic trends in metasedimentary rocks allow trea...

Sphalerite is a crucial host mineral for germanium (Ge) resources worldwide. However, the oxidation state (+2 or +4) of Ge and its substitution mechanism in sphalerite remain subjects of ongoing debate.

Stratabound base metal sulfide deposits within Neoproterozoic metavolcanic rocks and skarns in the Fujian Province are important Zn-Pb producers in China. To date, the inability to determine absolute ages and proper sources of Pb-Zn mineralization has led to conflicting ore genetic models. These include the metamorphosed volcanogenic massive sulfid...

Orogenic gold deposits are currently the world’s major source of Au, but uncertainty exists in the timing of mineralization relative to the ages of host rocks, metamorphism, and magmatism. Consequently, the origin and detailed evolution of ore-forming fluids have long been elusive. Apatite occurs widespread in various types of mineral deposits and...

Highly evolved granitic melts typically experience late-stage melt-melt and fluid-melt immiscibility as well as fluid-melt and fluid-rock interaction. These processes are particularly important in the formation of deposits of the rare metals Nb, Ta, W, and Sn. We document the relation between immiscibility and alteration processes and the partition...
