Abstract ：
The supergiant Shuangjianzishan (SJS) Ag-Pb-Zn deposit, located in the southern Great Xing'an Range (SGXR), is the largest Ag deposit in China. The SJS deposit can be divided into two ore blocks: the Shuangjianzishan ore block and the Xinglongshan ore block. Given the importance of the Xinglongshan ore block in the SJS deposit, our work is focused on the Xinglongshan ore block. The vein orebodies in the Xionglongshan ore block mainly occur in the NW-, NNW-, and NNE-trending fault zones, and its mineralization is mainly related to a deep concealed syenogranite. Here, we present new geochronology, isotope geochemistry, and fluid inclusion data for the Xinglongshan ore block and provide additional insights into the metallogenic mechanism of the deposit. The dating results show that the syenogranite related to the mineralization formed at approximately 137 Ma, which is coherent with some previous age determinations in sulfides from the ore deposit. The mineralization of the Xinglongshan ore block can be divided into four stages: sphalerite-arsenopyrite-pyrite-chalcopyrite-quartz stage (stage I), sphalerite-galena-pyrite-silver-bearing mineral-quartz stage (stage II), sphalerite-galena-silver-bearing mineral-quartz-calcite stage (stage III), and weakly mineralized quartz-calcite stage (stage IV). Four types of fluid inclusions (FIs) have been identified within quartz and calcite veins: liquid-rich, gas-rich, pure-liquid, and pure-gas FIs. The homogenization temperatures in the four stages exhibit a gradual decrease, with stage I ranging from 253 to 302 degrees C, stage II from 203 to 268 degrees C, stage III from 184 to 222 degrees C, and stage IV from 153 to 198 degrees C, respectively. The salinity for stages I, II, III, and IV falls within the ranges of 3.4-6.6 wt% NaCl eqv., 2.6-7.2 wt% NaCl eqv., 2.9-7.0 wt% NaCl eqv., and 1.2-4.8 wt% NaCl eqv., respectively, indicative of a low-salinity ore-forming fluid. The delta 18Owater and delta D values of the ore-forming fluid span from -13.9 parts per thousand to 7.4 parts per thousand and -145 parts per thousand to -65 parts per thousand, with delta 13CV-PDB values between -11.0 parts per thousand and -7.9 parts per thousand. These values suggest that the ore-forming fluid predominantly originated from a mixture of magmatic and meteoric water. The 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb ratios of sulfides range from 18.278 to 18.361, 15.530 to 15.634, and 38.107 to 38.448, respectively. These ratios imply that the ore-forming material was primarily derived from the Early Cretaceous granitic magma, which resulted from the mixing of depleted mantle- and crustal-derived magmas. The fluid mixing was the dominant mechanism for mineral precipitation. The Xinglongshan ore block belongs to a magmatic-hydrothermal vein-type deposit related to the Early Cretaceous syenogranite, and the Shuangjianzishan ore block belongs to an intermediate sulfidation epithermal deposit related to coeval subvolcanic rocks. The Ag-Pb-Zn mineralization at Shuangjianzishan is genetically related to the Early Cretaceous volcanic-intrusive complex.

Abstract ：
Selenium and Te are two important critical metals, which are often produced as by-products in Au-Cu deposits related to magmatic-hydrothermal systems, such as porphyry and skarn deposits. The Jilongshan Au-Cu deposit is a typical skarn deposit located in the middle and lower parts of the Yangtze River metallogenic belt. Previous studies show that it has valuable Se and Te resources, but their occurrence, particularly the relationship between the texture and composition of pyrite, and the enrichment mechanism of Se, Te, and Au remain unclear. Here, the textures and the major and trace elements of the Jilongshan pyrites were studied by using an optical microscope, EMPA, and LA-ICP-MS to reveal the occurrence of Se, Te, and Au in pyrite, as well as their genetic links with the pyrite mineralogical signature. The results show that there are three types of ores in the Jilongshan deposit, including granite porphyry-hosted, skarn-hosted, and carbonate-hosted ores. All of these ores contain major amounts of pyrite, which can be divided into four different generations. The first generation of pyrite (Py1) belongs to sedimentary genesis with a typical framboid texture and its Co/ Ni ratios are less than 1, whereas Py2, Py3, and Py4 belong to hydrothermal genesis and their Co/ Ni ratios are between 1.0 and 30.2. Selenium concentrations in Py2 and Py3 are relatively high (median, 138 ppm and 344 ppm, respectively), which are mainly present as isomorphism and a small amount as selenite in pyrite. Compared with granite porphyry-hosted and skarn-hosted ores, pyrite from carbonate-hosted ores has the highest Se concentrations. The latest generation of pyrite (Py4) contains the highest concentrations of Te (average, 140 ppm) and Au (average, 12 ppm) among the hydrothermal pyrites. Therefore, the precipitation of Se mainly occurs in pyrite during the early high-temperature stage, whereas higher concentrations of Te and Au are mainly enriched in pyrite during the late stage with low temperatures.

Abstract ：
The newly discovered Shuangjianzishan giant Ag-Pb-Zn deposit which located in the Southern segment of the Great Xing'an Range (SGXR), has controlled more than 18 000 t reserves of Ag, 1.9 Mt reserves of Zn, and 3.3 Mt reserves of Pb. Previous research has shown that Shuangjianzishan is a typical epithermal Ag-Pb-Zn deposit, however, mid-to high-temperature Cu-Sn (-W) mineralization are few studies. In this paper, a detailed mineralogical study reveals that a remarkable Cu-Sn (-W) mineralization is observed both in the upper tunnel and the deeper drill core samples. In the shallow ore-bodies, tin dominantly occurs as canfieldite in Pb-Zn-rich ores, minor as cassiterite-quartz veinlets. In the deep drill cores, tin occurs as cassiterite in the Cu-rich ores with the assemblage of quartz-arsenopyrite-chalcopyrite-stannite-(wolframite). Four primary paragenetic stages have been recognized. Stage I: cassiterite-quartz-arsenopyrite-chalcopyrite, including two sub-stage: cassiterite-arsenopyrite-pyrrhotite-quartz (stage I1) and sphalerite-chalcopyrite-galena-pyrite (stage I2); Stage II: galenasphalerite-silver minerals; Stage III: Quartz-silver minerals, and stage IV: pyrite-carbonate.Electron probe micro-analysis (EPMA) show that the early mineralization (stage I) is characterized by Fe-rich sphalerite, Co-rich pyrite, Se-rich canfieldite, and Se-Bi-rich galena, while the later mineralization (stage II-IV) contains Fe-depleted sphalerite, As-rich pyrite, and Sb-bearing silver minerals. Laser-ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis show that cassiterite has high contents of W, Fe, Sb, and Ti and depleted in Nb and Ta. Mineral associations and compositions implies a cassiterite-sulfide type tin mineralization in the Shuangjianzishan Ag-Pb-Zn deposit.A concealed granite porphyry intrusion was exposed in deep drill cores in the northwest part of the ore-field, with zircon U-Pb ages of (137.8 & PLUSMN; 1.1) Ma and (136.8 & PLUSMN; 1.0) Ma for fine-and coarse-grains granite, respectively. Bulk analysis shows that concealed granites are characterized by a highly fractionated, relatively reduced, and high K-calc-alkaline to alkaline, which belongs to A-type granites, and the remnant of Sn-bearing titanite suggests that it has the potential to provide the source of tin. Zircon U-Pb age (138-130 Ma) is well coupled with the previous data (ore-forming age, 136-129 Ma) of Shuangjianzishan, suggesting a close temporal and genetic relationship between tin mineralization and emplacement of the granite. This contribution implies that the Shuangjianzishan deposit may exist a middle-to high-temperature Cu-Sn (-W) mineralization center rather than a simple low-temperature hydrothermal system, and shows there is significant Sn-Cu mineralization potential in the peripheral and root zone of ore district.

Abstract ：
The Great Xing'an Sn-polymetallic metallogenic belt in Inner Mongolia is a potential district for indium (In) resources, where In mineralization has been discovered in the Dajing Sn-Cu polymetallic deposit, but the occurrence of In is not well understood. In this contribution, detailed mineralogical investigations of In-bearing minerals in the Dajing Sn-Cu deposit were conducted, based on fieldwork and ore petrography, combined with whole-rock analysis, EPMA, and LA-ICP-MS. Three ore-forming stages and six types of sphalerite are distin-guished. The highest In content (average 0.18 wt%) is observed in earlier exsolved sphalerite (Ia) in the Cu-Sn stage, other types of sphalerite contain relatively lower In concentration, with the average value ranging from 16 to 478 ppm. Overall, sphalerite in the Cu-Sn stage is more enriching in In than that in the Pb-Zn stage. Indium mainly occurs as solid solution in sphalerite. Other minerals such as stannite and chalcopyrite (Ia) exhibit relatively elevated In concentration (average >202 ppm). Cassiterite, pyrite, and pyrrhotite show negligible In content typically below 10 ppm. Combined with previous studies on ore-forming fluids, indium mineralization in the Dajing deposit is mainly associated with early-stage Cu-Sn fluids. The enrichment of In in sphalerite is probably attributed to the migration and diffusion of In in the Cu-Sn fluid during high-temperature conditions. Local dynamic processes (exsolution, diffusion, etc.) possibly have facilitated In mineralization in sphalerite. This study reveals the occurrence and distribution patterns of In in the Dajing deposit, promotes the recovery and utilization of In resources, and proposes new insights into the enrichment mechanisms and potential assessment of In.

Abstract ：
In this study, a comprehensive approach was adopted by combining micro-flotation, microscopy (optical and scanning electron microscopy), spectroscopy (X-ray diffraction and X-ray photoelectron spectroscopy), contact angle, and electron backscatter diffraction analysis techniques. The effects of differences in oxidation rates on the floatability and surface properties of high-sulfur epithermal pyrite (HSEP) in a shallow ore belt and porphyry pyrite (PP) in a deep ore belt of a hydrothermal deposit were investigated, and the relationship between the mineralogical properties and oxidation rate was studied. The experimental results showed that the discrepancy in the oxidation rate led to distinct differences in the flotation performances of HSEP and PP; the former exhibited a higher oxidation rate, and the floatability significantly decreased, whereas the latter exhibited a lower oxidation rate, and the floatability remained essentially unchanged. This is attributed to the difference in the crystal structures of the two types of pyrite. In addition to the various reaction sensitivities of the different crystal planes, the distribution densities of Fe and S atoms along the preferred orientation crystal plane of HSEP were higher than those of PP. This was conducive to the formation of Fe(III)-S and S2-, thereby accelerating the oxidation reaction.

Abstract ：
The Bor metallogenic belt in Serbia is a promising region for copper-gold (Cu-Au) resources, hosting numerous porphyry copper deposits, epithermal gold deposits and metallogenic prospects, such as the South Dulan and Vlaska exploration greenfield. Epidote alteration is integral to the propylitic and sodic-calcic alteration assemblages within this region. It is distinguished by the extensive occurrence of two primary epidote types: disseminated (Ep1) and veined (Ep2) epidote. In this study, comprehensive petrographic analysis reveals that in the propylitic zone, epidote mainly replaced hornblende (Ep1a) and plagioclase phenocrysts (Ep1b), coexisting with chlorite, apatite and titanite. In proximity to the potassic zone, epidote (E1c) coexists with biotite, while epidote (Ep2), chlorite, pyrite and chalcopyrite veinlets are observed near the ore body. Notably, Ep1 exhibits lower Fe and higher Mn contents in comparison to Ep2. Additionally, elements such as Ca, Al and Fe in Ep1a, and Ca, Fe, Mg, Mn and Ti in Ep1b, as well as Ca, Al, Fe and Mn in Ep1c, are introduced into the epidote through hydrothermal fluid interactions. Variations in trace element characteristics are evident among different epidotes. Specifically, Ep1a exhibits elevated Mg content (324-6050 ppm), Ep1b is notable for its high Na (22-942 ppm) and Sr (523-3075 ppm) contents, while Ep1c contains elevated K (24-445 ppm) and Na (41-103 ppm). Which suggest that disseminated epidote (Ep1) inherits the geochemical features from its precursor minerals. In comparison to disseminated epidote, epidote in veinlet exhibits higher Fe3+, Cu, Sn and REEs, along with lower contents of Pb, Sb and Sc, suggesting that these elements have been integrated into epidote through isomorphism substitution and influenced by fluids compositions, physical factors (temperature, pressure, etc.) and chemical parameters (speciation, pH, fO2, etc.), as well as mineral assemblages. Therefore, the trace element contents of Pb, Sb, Sc, Cu, Sn and REEs in epidote could serve as more appropriate indicators for mineral geochemistry in porphyry deposit hydrothermal centers.

查明蚀变和硫化物分带特征是建立斑岩-浅成低温铜金成矿系统的矿床模型与找矿预测的关键.Čukaru Peki铜金矿床是特提斯西段塞尔维亚Timok矿集区近几年新发现的超大型斑岩-浅成低温热液型铜金矿床(上部矿带资源量铜154万吨@2.45％,金86吨@1.37 g/t;下部矿带资源量铜1428万吨@0.83％,金295吨@0.17 g/t),矿体主要产于晚白垩世安山岩中.目前关于该矿床热液蚀变与矿化分带特征及其找矿方向的研究程度相对较低,本文根据钻孔编录信息,利用短波红外(SWIR)光谱技术、光学显微镜和电子探针分析技术,对典型剖面钻孔中的岩矿石样品开展研究,厘定了Čukaru Peki铜金矿床的热液蚀变和金属硫化物分带特征.研究发现该矿床具有垂向分带特征:下部斑岩铜金矿体、中部斑岩-浅成低温过渡铜金矿体和上部高硫型浅成低温热液铜金矿体.矿区热液蚀变分带特征明显,其中斑岩铜金矿体以岩体为中心,由内向外可划分为钾硅酸盐化带、青磐岩化带、绿泥石-白云母带和石英-白云母带,绿泥石-白云母带中的白云母SWIR Al-OH 2200 nm吸收峰波长高于石英-白云母带;斑岩向浅成低温过渡铜金矿体发育硬水铝石-叶蜡石带;高硫型浅成低温铜金矿体发育高级泥化蚀变,由内向外可划分为石英-明矾石带、地开石-高岭石带和蒙脱石带.Čukaru Peki铜金矿床的金属硫化物组合具有明显的分带特征,斑岩铜金矿体由下至上表现为:黄铜矿+斑铜矿→黄铁矿+黄铜矿+(磁铁矿±赤铁矿);过渡铜金矿体主要为:砷黝铜矿+(斑铜矿+黄铜矿+蓝辉铜矿+铜蓝)组合;高硫铜金矿体为硫砷铜矿+铜蓝组合.总体上,矿床下部为Cu-Fe-S体系,中部贯穿Cu-As-Sb-S体系,向上转变为Cu-S体系.硫化物组合从深部早阶段的高温低硫化态转为中浅部晚阶段的低温高硫化态.结合化探分析资料,建立热液蚀变和硫化物分带模型,推测Čukaru Peki铜金矿床北西部存在很大的找矿潜力.Čukaru Peki铜金矿床的研究可以为我国紫金山金铜矿床深边部增储、冈底斯成矿带寻找晚白垩世斑岩-浅成低温热液铜金矿床提供一定参考.

特提斯成矿域发育多个世界级斑岩-浅成低温铜金矿床,Apuseni-Banat-Timok-Srednogorie(ABTS)斑岩-矽卡岩-浅成低温铜金成矿带位于特提斯成矿域西段.Timok矿集区位于ABTS成矿带中部,区内矿床成矿峰期主要集中在晚白垩世.Zlatno Brdo(以下简称ZB)金矿床是Timok矿集区近年新发现的金矿床(金资源量约30 t,平均品位1.11 g/t).该矿床矿体受断裂控制,呈脉状产于晚白垩世斜长角闪安山岩中,其矿床类型和找矿潜力目前仍不清楚.本文对热液蚀变矿物和硫化物进行电子探针分析,发现ZB金矿床发育中硫化态的硫化物组合(黄铜矿+黝铜矿)、与金矿化相关的低铁闪锌矿(FeS摩尔比平均为5.8％,n=11)和富Mn碳酸盐(MnO百分含量平均为2.68％,n=46),以及矿石中含与热液重晶石共生的金碲化物.利用探矿者(MinESoft)三维建模软件,分别对蚀变带和矿体进行建模工作,结合区域地质特征,本文认为ZB金矿床为Timok矿集区首例中硫化型浅成低温热液金矿床,且该矿床北西方向具有较大的找矿潜力,热液重晶石可作为找矿标志之一.此外,同属于特提斯成矿域的冈底斯斑岩铜矿成矿带近年来发现多处晚白垩世大-中型矽卡岩铜金矿床,且该带普遍发育100～80 Ma岩浆岩,暗示冈底斯斑岩-矽卡岩铜金矿床外围有寻找晚白垩世浅成低温热液金矿床的潜力.
