The investigated Tioueine Ring Complex is among them, with two major units: a weakly evolved calc-alkaline central unit containing monzogranite and granodiorite, and a highly evolved alkali feldspar granite-dominated major outer unit that hosts magmatic to magmatic-hydrothermal LREE-dominant mineralization. The Tioueine Ring Complex is a mantle-derived A₁-type granitoid complex that crystallized at ca. 600 Ma during a post-orogenic to anorogenic episode of the Pan-African orogeny. Its parental magmatic system is characterized by high concentrations of alkali elements, with moderate total REE₂O₃ (TREE₂O₃) contents up to 0.2 wt%; allanite is the major REE-rich mineral, with limited proportions of apatite, xenotime, and rare monazite. Primary mineralization resulted from low degrees of partial melting of an enriched mantle source that produced reduced ferroan REE-rich magma following advective mantle heat input. The derivative melt may have experienced crustal assimilation and crystal fractionation that caused further enrichment in HFSE and REE before reaching the solidus. A late- to post-magmatic-hydrothermal event allowed limited secondary enrichment of REE by causing allanite breakdown to form REE-fluorocarbonate minerals. Fluid—rock interaction likely resulted from magmatic-hydrothermal F- and CO₂-rich aqueous fluids and late meteoric hydrothermal fluids that circulated through ring faults. The Tioueine Ring Complex exhibits elevated REE concentrations that warrant follow-up sampling and drilling to assess its economic viability. However, despite REE enrichment in A-type granites globally, the role of F-rich fluids in remobilizing REE from magmatic allanite to form hydrothermal REE-fluorocarbonates remains poorly constrained.

As a widely developed alteration mineral in magmatic-hydrothermal deposits, white mica has been successfully applied to the exploration of porphyry, epithermal, volcanogenic massive sulfide (VMS) deposits based on its short-wave infrared (SWIR) spectrum. However, the exploration vectors of white mica vary among different types of deposits. The hyperspectral exploration vector of white mica in tungsten ore remains to be improved, and the study on the significance of trace element indication of white mica is still immature. In this study, the giant Dahutang tungsten ore field in Jiangxi Province is selected as the research object. The research focuses on five types of intrusions associated with mineralization in Dahutang: biotite granodiorite, porphyritic biotite granite, porphyritic fine-grained biotite granite, fine-grained muscovite granite, and granite porphyry. The significance of spectral and geochemical characteristics of white mica for tungsten ore exploration is discussed through comprehensive study on the characteristic parameters, major and trace elements of white mica SWIR spectrum in different intrusions. The results show that the high Pos2200 (Pos2200 &gt; 2209 nm) and low SWIR-IC (SWIR-IC &lt; 0.9) values of white mica in Dahutang can be used as important vectors of mineralization, which mainly occurred in the inner and outer contact zone of biotite granodiorite of Jinningian period (Tonian, ∼1000–800 Ma) and Yanshanian period (Jurassic to Cretaceous, 200–90 Ma). The white mica in ore-bearing intrusions are characterized by high Si, Mg, Fe, F, Li, Sn, Cs and low Al, Na, whereas those in ore-barren intrusions show the opposite features. In addition, the Pos2200 value of SWIR spectrum of white mica in intrusions is positively correlated with Si, Mg, Fe, F, Li, Sn and Cs, and negatively correlated with Al and Na. The value of SWIR-IC is primarily controlled by temperature and exhibits a weak correlation with the major and trace elements in white mica. The high contents of F, Li and Cs in magmatic white mica also indicate that the magmatic evolution of ore-bearing intrusions has higher degree than ore-barren intrusions. The hydrothermal white mica in biotite granodiorite and porphyritic biotite granite all show higher content of V, Sc and W, indicating that metallogenic environment is relatively reduction conditions. Contrasting with other types of deposits, the decline in temperature and rise in fluid pH value prompt the substitution of Tschermak’s component towards Si, Mg, and Fe enrichment, rendering phengite a crucial mineralization indicator in tungsten deposits.

This study presents an integrated geochemical investigation of apatite from the barren monzogranite porphyry (BMP) and ore-related granite porphyry (OGP), alongside scheelite from successive mineralization stages (prograde skarn, retrograde skarn, and quartz-sulfide), to decipher the petrogenetic and hydrothermal evolution. Apatite from the OGP exhibits distin ct geochemical signatures, including lower contents of FeO, MgO, and Sr, a stronger negative Eu anomaly, and higher HREE and Y contents, suggesting a higher degree of fractional crystallization compared to the BMP. Additionally, the lower SO₃ content, higher MnO content, and more pronounced negative Eu anomaly in OGP apatite indicate that the ore-forming magma evolved under reduced conditions. The extremely low Cl content and X_F/X_Cl ratios in OGP apatite provide definitive evidence for large-scale fluid saturation and exsolution from the magma. The geochemical signature of scheelite, characterized by its Y/Ho ratios, Sr and Mo contents, and LREE-enriched patterns, points to a predominant magmatic origin for the ore-forming fluids. Notably, variations in Mo content, Eu and Ce anomalies across different scheelite generations reflect significant fluctuations in fluid oxygen fugacity (ƒO₂) during mineralization. During the prograde skarn stage (Sch-I), which formed under relatively reduced conditions, Mo-poor scheelite was precipitated. In the retrograde skarn stage (Sch-II), a sharp increase in ƒO₂ led to the incorporation of Mo⁶⁺ into the scheelite lattice, forming Mo-rich scheelite. During the quartz-sulfide stage (Sch-III), ƒO₂ decreased back to relatively reduced conditions, triggering the reduction of Mo⁶⁺ to Mo⁴⁺, which subsequently precipitated as MoS₂, generating Mo-poor scheelite in late-stage.

Cryptic variation is characteristic for the magnetitites with a general trend of upward depletion of the Cr concentrations in magnetite, which is occasionally inverted. This work applies Laser Induced Breakdown Spectroscopy (LIBS) and micro-X-ray Fluorescence (µXRF) mapping to examine the element trends in magnetitites on a µm-scale along a drill core. These methods provide continuous 2D element and mineral distribution maps. The LIBS and µXRF data were validated using thin section microscopy and electron probe microanalysis. The Cr distribution confirms the general trend of upward depletion and shows repeated increases which mostly correlate with plagioclase or sulfide lenses. Vanadium shows an upward increase within the magnetitite layer which rules out simple fractional crystallization models for the magnetitite formation. Furthermore, the contact zones of magnetitite and anorthosite exhibit abundant symplectic intergrowth of olivine and plagioclase with significantly higher An# in the symplectic plagioclase and higher Mg# in olivine accompanied by amphibole and mica, suggesting a flow of a more mafic melt and the interaction with a hydrous melt.

These results are consistent, within error, with the emplacement age of the fine-grained porphyritic monzogranite (154–150 Ma), indicating that Li–Sn polymetallic mineralization in the Jiuyishan area occurred during the Early Yanshanian period. Two main granite types are developed in the Zhongchong deposit: medium- to coarse-grained porphyritic-like syenogranite and fine-grained porphyritic monzogranite. Geochemical analyses show that both granites are silica- and alkali-rich but depleted in Ca and Mg, with peraluminous to weakly peraluminous compositions (A/CNK = 0.98–1.19). The syenogranite contains significantly higher total REE contents than the monzogranite, with LREE-enriched, right-inclined patterns, whereas the latter exhibits a pronounced tetrad effect. Both granite types are enriched in Rb, K, Th, U, Nd, and Hf but depleted in Ba, Sr, Nb, and Ti, with the fine-grained monzogranite showing stronger enrichment–depletion signatures. These characteristics suggest that the syenogranite and monzogranite represent cumulates and residual melts derived from a common parental magma, with the latter showing higher degrees of differentiation and stronger rare-metal enrichment, thereby possessing greater metallogenic potential. Electron microprobe analyses of zinnwaldite from greisen ores in the Zhongchong deposit are presented in this study.

To assess whether its genesis differs from that of shallow gold deposits, this study conducted a systematic investigation involving petrography, fluid inclusions, geochronology, and isotope geochemistry. Four stages of hydrothermal veins were identified: pre-ore veins containing milky quartz and minor disseminated pyrite; main-ore veins consisting of gold-bearing pyrite, quartz, and minor muscovite; late-ore stage veins consisting of (gold-bearing) pyrite, galena, chalcopyrite, and quartz; and post-ore veins characterized by calcite, quartz, and minor pyrite. Gold mineralization primarily occurred during the main-ore stage, with minor mineralization in the last-ore stage. Hydrothermal monazite and apatite U-Pb dating constrain the timing of gold mineralization to approximately 120 Ma. The ore-forming fluid was a CO₂-H₂O-NaCl ± CH₄ system with salinity of 1.0–12.2 wt% NaCl equiv. and temperatures of 195 °C–372 °C. Fluid immiscibility during the main- and late-ore stages, coupled with water–rock interaction led to gold precipitation.

These isotopic characteristics indicate that the Zhaoxian deposit shares a common fluid source with other deposits in the Jiaojia goldfield and across the Jiaodong Peninsula, likely derived from devolatilization of the metasomatized subcontinental lithospheric mantle.
