Abstract :
云南文山州小洞锑矿床处于滇东南锑矿带,矿体赋存于寒武系中统田蓬组下段硅质岩中.前人认为其属于变质改造的热水沉积型锑矿床,但关于该矿床的成岩成矿机制和矿床成因类型等问题仍有争议.对赋矿围岩硅质岩的主微量分析显示,w(SiO2)为 84.70%~97.11%(均值 92.19%),w(Al2O3)为0.63%~6.08%(均值 3.56%),ΣREE为(20.43~77.54)×10-6,稀土配分曲线右倾,δEu值为0.66~1.57(均值 0.88),δCe值为 0.95~1.15(均值 1.07),形成于大陆边缘的非热水沉积环境,成分受陆源输入的控制.辉锑矿 LA-ICP-MS分析揭示了其微量元素的主要耦合替代机制为 2Sb3+↔As3++(Cu++Pb2+).辉锑矿的S同位素分析显示δ34S值变化范围较窄(0.42‰~4.91‰),暗示成矿物质来源于岩浆,成矿热液可能与老君山岩体活动相关,或者为深部隐伏岩体带来的热液.综合分析认为,小洞锑矿床的赋矿围岩与热水沉积无关,成矿物质主要来源于岩浆热液.岩浆活动后期的含矿热液流体沿断裂带运移,在层间虚脱带富集成矿,属于受断裂控制的热液型锑矿床.

Abstract :
The Lawu Cu-Pb-Zn deposit is situated in the eastern part of Nyainqentanglha metallogenic belt, Tibet. It represents a rare indium (In)-bearing and tin (Sn)-poor skarn system, however, the occurrence, distribution, and endowment of In, along with their geochemical controls, remain poorly constrained. In this contribution, we conducted a comprehensive mineralogical study of sulfides using microscopic observation, electron probe microanalyzer (EPMA), and laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS). Based on mineral assemblage and textural relationships, four types of sphalerite are identified: sphalerite I as microinclusions within chalcopyrite and pyrrhotite, sphalerite II with abundant mineral inclusions, sphalerite III exhibiting chalcopyrite disease with watermelon texture, and sphalerite IV displaying a relatively clean texture with minimal inclusions. Sphalerite I is enriched in In, Cu, Cd, and Mn, whereas sphalerite II and sphalerite IV exhibit variable contents of In, Sn, Cu, Mn, Co, Se, and Ag. Trace elements, such as In, commonly occur in sulfides via isomorphic substitution, with minor amounts present as micron-scale mineral inclusions (e.g., Cu in sphalerite; Pb and Bi in sphalerite, chalcopyrite, and pyrite). From the perspective of In content in minerals, In is mainly hosted in sphalerite (average >400 ppm). Chalcopyrite also shows relatively elevated In content (average similar to 200 ppm). Pyrrhotite, pyrite, and arsenopyrite typically contain negligible In content, generally below 10 ppm. According to the GGIMFis geothermometer calculations, the crystallization temperatures of sphalerite II to sphalerite IV are as follows: 378 to 427 degrees C (average = 398 degrees C) for sphalerite II, 389 to 399 degrees C (395 degrees C) for sphalerite III, and 338 to 375 degrees C (356 degrees C) for sphalerite IV. The In, Cu, and Co contents in sphalerite increase with crystallization temperatures, implying that their incorporation is primarily controlled by the temperature of oreforming fluids. Combined with the published sphalerite dataset, a strong correlation is inferred between In and Sn, Cu, or Fe. Notably, Sn-poor Zn-polymetallic skarn systems represent strategic targets for In resource exploration. This finding refines the understanding of In occurrence and enrichment in Sn-poor skarn systems, providing insights applicable to similar geological environments.

Abstract :
The Dulong deposit is a major cassiterite-sulfide skarn deposit in Southwest China, hosting significant In resources (7,000t). Although the occurrence of In has been studied in detail, its spatiotemporal distribution and controlling factors remain poorly understood. This study therefore systematically analyzes fluid inclusions, chlorite geochemistry, and combined with published In contents from sphalerite to comprehensively examine ore-forming fluid evolution and its impact on In mineralization. The fluid inclusions data show that S-type, Ltype, and V-type can be recognized at Dulong. The S-type inclusions predominantly occur in pyroxene from prograde stage and coexist with L-type inclusions, suggesting that fluid boiling occurred. The homogenization temperature and salinity of fluids show a significant decrease from prograde stage (468-560 degrees C, 44.7-49.6 % NaCleqv) to retrograde stage (365-375 degrees C, 3.1-3.7 % NaCleqv), indicating potential mixing with meteoric waters. From retrograde to sulfide stage, both temperature and salinity decrease slightly (from 365-375 degrees C to 210-365 degrees C, and 3.1 %-3.7 % NaCleqvto 0.3 %-2.6 % NaCleqv, respectively), inferring that fluid cooling probably was the key factor for sulfide precipitation and associated In enrichment. The chlorite results show that, from bottom to top of the open pit, this variation in trace element concentrations is dominantly related to the decrease in temperature that occurs during the migration of hydrothermal fluid. The fluid temperatures correlate with increased In concentrations in sphalerite, suggesting temperature controls In enrichment. Additionally, the Ti/Sr ratio in chlorite indicate the possible hydrothermal center at the bottom of the Manjiazhai ore block (approximately 1152 m-depth), implying that the Dulong deposit is probably a distal skarn deposit.

Abstract :
The Dulong deposit is a world-class Sn-polymetallic deposit with indium mineralization, which is associated with highly evolved Late Cretaceous S-type granites, indicating the magmatism is crucial for the indium enrichment. Through integrated in-situ geochemical analyses of mica and apatite across variably fractionated granites and country rocks, this study reveals a systematic evolution of redox conditions, halogen chemistry, and metal enrichment during magmatic differentiation. As magmatic evolution progresses, indium and tin contentratons in mica increase progressively, reaching peak vales in the late stage of evolution at Dulong deposit. Notably, indium concentration in muscovite is greater than that in biotite, when muscovite converts into phengite. Apatite and mica compositions indicate low oxygen fugacity (fO(2)) magmatism. Fe-rich biotite in Sn-In-bearing granites contrasts with Mg-biotite in Sn-poor systems, with Fe3+/(Fe2++Fe3+) ratios < 0.2 confirming reduced fO(2) conditions conducive to indium melt incorporation. Apatite geochemistry reinforces this: low SO3 (0.01-0.08 wt%), As depletion (14.54-42.10 ppm), and marked negative Eu anomalies (Eu/Eu* <0.4). Multi-proxy evidence collectively confirms a reduced magmatic system. Integrated proxies confirm a reduced magmatic system where progressive redox reduction during differentiation fosters indium enrichment, enhancing metallogenic potential. Concurrently, apatite halogen signatures track magmatic evolution: sustained F enrichment with late Cl spikes aligns with mantle-derived inputs evidenced by mafic enclaves. Although Cl concentrations remain low in the early magmatic stages, their subsequent dramatic increase correlates temporally and genetically with marked enrichment of In and Sn during later evolutionary phases. The mixing of mantle-derived magmas may bring in Cl-rich fluids/melts and related ore-forming materials, which promotes indium mineralization. The concurrent enrichment of halogen elements, F and Cl, plays a crucial role in the extraordinary accumulation of indium.

Abstract :
Silicate phases coexisting with ore minerals are often overlooked when constraining ore-forming processes, even when they host significant concentrations of commodity metals and may subsequently release these metals to form discrete mineral phases. Relationships between garnet growth and tungsten mineralisation are studied using W-rich garnets (up to 3542 ppm) from the oxidised Fujiashan W(-Cu-Mo) skarn, China. Compositional heterogeneity in garnet, expressed as core-to-rim texture, relates to successive two-stage fluid infiltration. Tungsten shows strong positive correlations with As, Mo and In, with all four elements appearing to be structurally bound. Scheelite is expected to form during the replacement of W-rich garnet by retrograde minerals. Scavenging large quantities of W by andradite garnet and the lack of intense retrograde alteration may be critical factors contributing to low W grades observed in oxidised skarns. Our findings underscore the importance of gangue mineral growth and breakdown in influencing the distribution of certain ore metals.

Abstract :
Understanding elements uptake and release from minerals in source rocks is crucial for comprehending critical metals accumulation, yet the mechanisms and kinetics of element mobilization at the atomic scale remain mostly unknown. Here, we analyzed the distribution of cobalt (Co) in natural pyrite from a Cu-Co ore deposit and found that metals distribution is best described by steady-state diffusion with constant flux and concentration-dependent diffusivities, rather than transient-state diffusion with time-evolving concentrations. First-principles calculations and diffusion modelling further demonstrate that this diffusion is accelerated by vacancy pathways and is far more efficient than traditional vacancy-mediated lattice diffusion, with element transfer rates higher by almost two orders of magnitude. We conclude that steady-state lattice diffusion induced by vacancies in the presence of fluid can be an efficient mechanism promoting the preferential release of metals into ore fluids and the accumulation of metals during ore formation.

Abstract :
Quartz chemistry is important for revealing fluid sources and evolution in hydrothermal deposits, but such information is lacking for many epithermal systems and deposit types. To investigate quartz chemistry in this system further, we collected representative samples of quartz from adularia-sericite epithermal Ag deposits in China and determined their chemical compositions. In adularia-sericite epithermal Ag-bearing systems, magmatic quartz from porphyry intrusions and host subvolcanic rocks displays SEM-CL spectral peaks at 360 and 415 nm and exhibits homogenous CL or weak zonal textures (alternating growth zones within individual quartz crystals). Trace elements in magmatic quartz have the lowest Sb concentrations (median = 0.1 ppm; n = 80). Hydrothermal quartz can be classified into type I and type II by CL false color and CL spectral peaks. Hydrothermal type I quartz has spectral peaks at 360 and 415 nm; it exhibits zonal or sector textures and is associated with base metal sulfides and minor Ag mineralization. Such hydrothermal type I quartz has low Sb concentrations (median = 4.5 ppm; n = 839), contains liquid-rich fluid inclusions, and is formed by cooling. The cooling trend is indicated by a positive correlation between the concentrations of Sb and Al, as well as between Li and Al. Hydrothermal type I quartz has an Fe center by electron spin resonance, whereas other centers are missing or weak at room temperature. In general, hydrothermal type II quartz mantles type I quartz. Hydrothermal type II quartz has an ultrahigh-intensity peak (by several orders of magnitude) at 580 nm, zonal textures, and is associated with abundant Ag mineralization. Hydrothermal type II quartz has the highest Sb concentrations (median = 71 ppm; n = 185), which remain constant as Al decreases on an Sb vs. Al plot. This quartz has colloform, bladed, or zonal textures and contains coexisting liquid- and vapor-rich fluid inclusions indicative of boiling. Additionally, this quartz has a significantly higher E'1 center intensity, suggesting a high concentration of oxygen vacancies associated with rapid crystallization. The mineral paragenesis, analytical results, and geochemical models show that, in these Ag-bearing epithermal systems, hydrothermal type I quartz associated with base metal sulfides precipitated during cooling, whereas subsequent growth-zoned hydrothermal type II quartz with high Sb concentrations and Ag-minerals precipitated during boiling. These results suggest that the CL texture and spectra, trace elements, and electron spin resonance data of quartz could identify veins with potential for Ag mineralization in epithermal systems.

Abstract :
The magmatic evolution process can be reconstructed by using the mineralogical data from various alkaline mafic minerals from different stages of magmatism. This study presents an integrated bulk-rock elemental composition, zircon U-Pb dating, Lu-Hf isotopic geochemistry, and electron probe microregion analysis of key mafic minerals in miarolitic granites from Gushan area, coastal Fujian Province. The Gushan granite hosts typical alkaline mafic minerals, such as arfvedsonite and aegirine, characterized by high silicon content, alkali enrichment, low magnesium and calcium, and reduced iron and aluminum levels. These rocks are classified as para-aluminous to peralkaline and exhibit negative Eu anomalies, enrichment in light rare earth elements (LREE), and depletion in heavy rare earth elements (HREE). Granites are enriched in K, Rb, Th, U, while being depleted in Ba, Sr and high field strength elements Nb, Ta, P and Ti, identifying them as highly fractionated alkaline A-type granites. LA-ICP-MS zircon U-Pb dating yields an age of approximately 95 Ma, indicating their formation in early Late Cretaceous. The average Delta FMQ of zircon is +5.36, indicating that the magma possessed a high oxygen fugacity. Alkaline mafic minerals such as arfvedsonite and aegirine crystallized during the late stage of magmatic evolution. Aegirine characterized by high silicon, sodium and iron contents, along with low titanium, magnesium, aluminum and manganese. Arfvedsonite exhibits enrichment in alkali and iron, high silicon content, and depletion in calcium. The zircon epsilon(Hf) (t) values of the alkaline granite range from -1.8 to +5.4, with two-stage model ages (t(DM2)) spanning from 810 Ma to 1278 Ma. The magma source is attributed to partial melting of enrich mantle-derived continental crust rocks formed during contemporaneous underplating. This process occurred in an extensional environment driven by the subduction and rollback of the Pacific plate.

Abstract :
The Jilongshan Au-Cu skarn deposit is located at the Jiurui ore district of the Middle-Lower Yangtze River metallogenic belt (MLYB), which is a significant metallogenic belt for dispersed elements. The Jilongshan deposit hosts abundant critical metal elements (e.g., Se, Te, and Bi) and shows potential for the comprehensive utilization of these critical mineral resources. This study examines the mineralogical textures and compositions of sulfides and sulfosalts from the Jilongshan deposit through EPMA, TIMA, and LA-ICP-MS analyses to clarify the nature of the occurrence and distribution of Se and Te. Based on the host rocks, the ores can be divided into porphyry-hosted, marble-hosted, and skarn-hosted types. Selenium content is significantly higher in porphyry- hosted and skarn-hosted ores compared to marble-hosted ore, while Te is most abundant in marble-hosted ore. Apart from rare minerals such as clausthalite (PbSe), hessite (Ag2Te), and hedleyite (Bi7Te3), Se and Te predominantly occur as isomorphism within pyrite (similar to 70 %) and tetrahedrite (similar to 20 %). On the basis of mineral assemblages and textures, tetrahedrite can be recognized as three generations, including Ttr1 (replacing Fe-Cu sulfides), Ttr2 (intergrown with Pb-Zn sulfides), and Ttr3 (replacement of last pyrite). Selenium is enriched in minerals precipitated in the Fe-Cu stage, including hydrothermal pyrite, chalcopyrite, and Ttr1, with the average of 345 ppm, 183 ppm, and 592 ppm, respectively, while Te mainly concentrates in minerals formed in the Pb-Zn stage, such as galena (143 ppm), Ttr2 (3112 ppm), and Ttr3 (489 ppm). These findings align with previous studies on the Se-Te relationship and may indicate that Se is more likely to be enriched at a higher temperature, while Te exhibits the opposite trend. The variation in sulfur fugacity within fluid systems may also play a role in the enrichment of these critical elements. Additionally, the regional distribution and enrichment of Se and Te in the porphyry-skarn deposits of the MLYB also shows certain regularity. Selenium is more likely to be enriched in high-temperature porphyry ores, while Te is most abundant in relatively low-temperature interlayer ores.
