Abstract ：
特提斯成矿域西段塞尔维亚Timok矿集区的Čukaru Peki属于典型的斑岩-高硫型超大型铜金矿床,具有典型的矿化蚀变分带.前人开展了该矿床的硫化物和蚀变分带的研究,但对于普遍发育的蚀变矿物——绿泥石的地球化学特征和找矿勘查指标缺乏研究.为此,文章以Čukaru Peki铜金矿床中斑岩型矿体的绿泥石为研究对象,利用显微镜、电子探针(EPMA)和激光剥蚀电感耦合等离子体质谱仪(LA-ICP-MS)分析技术,厘定了绿泥石类型和主、微量元素特征,探讨其找矿标志.结果表明,绿泥石的产状可划分为3种,分别为青磐岩化带Chl-1、绢英岩化带Chl-2和钾化带Chl-3,其中,青磐岩化带的绿泥石可进一步分为交代型(Chl-1a)和浸染型(Chl-1b)两个亚类.3类绿泥石均属于富Mg型绿泥石,其中,Chl-1绿泥石为斜绿泥石-鲕绿泥石,Chl-2和Chl-3绿泥石为透绿泥石-蠕绿泥石.绿泥石替代机制以Fe2+、Mg2+替代为主,同时存在TK((Si4+)Ⅳ+(Fe2+,Mg2+)Ⅵ=(Al3+)Ⅳ+(Al3+)Ⅵ)型和DT(2(Al3+,Fe3+)Ⅵ+□ Ⅵ=3(Fe2+,Mg2+)Ⅵ)型 2类替代机制.根据绿泥石温度计可知,钾化带的Chl-3绿泥石形成温度(约325℃)高于青磐岩化带的浸染型绿泥石(约257℃).相比于外围青磐岩化带的Chl-1,靠近热液中心的Chl-2和Chl-3绿泥石具有更高的Ti、K、V、Cr、含量和Ti/Pb、Ti/Li、Ti/Sr等比值,其Ti/Sr和Ti/Li比值随距矿体距离增大而降低,推测矿化热液中心在Čukaru Peki铜金矿床西北侧深部(1～2 km),并提出绿泥石Ti/Sr比值等可作为Čukaru Peki斑岩铜金矿体的找矿勘查指标.

Abstract ：
There are a large number of fahlores recognized in the Zijinshan ore field, including tetrahedrite, tennantite, Zn-rich tetrahedrite, goldfieldite, Bi-rich tetrahedrite, etc. The changes in their mineral composition have significance for the evolution of the ore-forming environment. This article presents a detailed study of the fahlores using electron probe analysis. The results indicate that in the Zijinshan Au-Cu deposit, fahlores are Te-rich in shallow zones and Zn-rich in deep zones. The Zijinshan Xi'nan deposit is generally Zn-rich, with a Bi-rich in middle levels. The Longjiangting deposit is Sb- and Zn-rich in shallow zones and As- and Bi-rich in deep zones, whereas the Yueyang deposit is Sb- and Zn-rich in shallow zones and Bi-rich in deep zones. The fahlores in the Zijinshan ore field often show zoning in backscattered images due to As and Sb variations. From the porphyry to high-sulfidation stages, fahlores evolve from Fe-rich to Zn-, Bi-, and Sb-rich, and finally to Te-rich. From the porphyry to low-sulfidation stages, fahlores transition from Bi-rich to Zn-rich and eventually to Ag-rich compositions. The discovered mineral assemblages of the fahlores are of great significance for understanding the framework of complex porphyry shallow hydrothermal environments and prospecting for underlying porphyry ore bodies in the Zijinshan ore field.

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 ：
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.

Abstract ：
The Veliki Krivelj large porphyry-skarn Cu deposit in Serbia is located in the Timok metallogenic district on the western margin of the Tethyan metallogenic domain. The ore bodies are predominantly hosted in altered andesite, quartz diorite porphyry, skarn and marble, and are structurally controlled by NNW-trending faults. Previous studies have focused on porphyry Cu mineralization, while systematic understanding of skarn Cu mineralization remains limited. Based on detailed geological investigations of skarn orebodies, this study focuses on the geochronology and elemental geochemistry of garnet within them. Detailed petrographic investigations reveal that garnets occur in three lithological units: tuffaceous hornfels (Grt I), quartz diorite porphyry (Grt II), and marble (Grt III), exhibiting multistage compositional zoning: (1) Grt I displays core-to-rim evolution from Grt Ia (Gro69-75And25-30) → Grt Ib (Gro44-63And34-55) → Grt Ic (Gro0-14And86-99), marked by progressive depletion in grossular (Gro) and enrichment in andradite (And); (2) Grt II transitions from Al-rich cores (Grt IIa: Gro33-46And52-66) to Fe3+-dominant rims (Grt IIb: Gro1-9And90-98); (3) Grt III comprises pure andradite (Gro0-4And95-99). Trace element analyses indicate that Grt Ia and Grt Ib display weak HREE enrichment with LREE depletion, weak or absent Eu anomalies, and uniform Y/Ho ratios, suggesting formation in a reduced, low water/rock ratio, near-neutral closed system dominated by magmatic fluids. In contrast, Grt Ic, Grt IIa, Grt IIb, and Grt III exhibit LREE enrichment with HREE depletion, pronounced positive Eu anomalies, and variable Y/Ho ratios, indicative of formation in an oxidized, high water/rock ratio, weakly acidic open system involving both magmatic fluids and variable contributions from meteoric water. Garnet U-Pb dating constrains skarn Cu mineralization at 86.4 ± 1.9 Ma, coeval with porphyry mineralization (∼88 Ma) and quartz diorite porphyry emplacement (85–87 Ma). Comprehensive analysis suggests that the porphyry and skarn mineralization belong to the products of the same magmatic-hydrothermal mineralization system, and the quartz diorite porphyry may be the parental rock of the Veliki Krivelj skarn. This study provides critical mineralogical constraints for guiding further exploration in the mining area. © 2025

Abstract ：
Clogauite, ideally PbBi4Te4S3 is the new n = 1 member of the aleksite series, PbnBi4Te4Sn+2, where n is the homologue number. Clogauite is named from the type locality, the Clogau gold mine, Dolgellau Gold belt, Gwynedd, North Wales, United Kingdom. The mineral and name have been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (IMA2023-062). The aleksite series is an accretional homologous series in which each member is derived from the same 5-atom tetradymite archetype. Clogauite crystallises in the trigonal crystal system (space group: P3m1, #164). Three distinct polytypes of clogauite are recognised, corresponding to identical chemistry but different layer sequences, expressed as (57), (5559) and (557.559), respectively, in reference to the number of atoms in individual layer sequences. These are clogauite-12H, a = 4.277(4) & Aring;, c = 23.46(14) & Aring;, V = 371.598 & Aring;(3) and Z = 1; clogauite-24H, a = 4.278(4) & Aring;, c = 46.88(31) & Aring;, V = 743.053 & Aring;(3) and Z = 2; and clogauite-36H, a = 4.278(4) & Aring;, c = 70.36(32) & Aring;, V = 1115.283 & Aring;(3) and Z = 3. Clogauite is opaque, with a pale grey colour in reflected light. Reflectance is higher than tetradymite or galena. Bireflectance and anisotropy are strong. Structural data were determined from measurement of atomic-scale HAADF STEM imaging showing the internal arrangement of component atoms and characteristic selected area electron diffraction patterns for each polytype. The structures were then further constrained from ab initio total energy calculations and structure relaxation using density functional theory (DFT) using the measured parameters as input data. The relaxed crystal structure for each polytype was modelled to generate crystallographic information files (cif). STEM and electron diffraction simulations based on the crystallographic information data obtained from the DFT calculations show an excellent match to the empirical measurements.

Čukaru Peki铜金矿床位于特提斯成矿域西部塞尔维亚Timok矿集区,是近几年新发现的超大型斑岩-浅成低温热液型铜金矿床.该矿床主要产于晚白垩世角闪斜长安山岩中,具有明显的蚀变分带特征,是研究蚀变矿物勘查指标体系的理想对象.笔者结合钻孔编录信息,利用显微镜、电子探针和LA-ICP-MS分析技术,对该矿床中的绿帘石进行矿物化学成分分析.根据产状可将绿帘石划分为2类,分别为赋存于绢英岩化带中的绿帘石(Ⅰ型绿帘石)和赋存于青磐岩化带中的绿帘石(Ⅱ型绿帘石).电子探针分析结果表明,2类绿帘石中的n( Al)与n(Fe)、n(Ca)与n(Mn)均呈现负相关关系,n(Al)、n(Fe)、w( Mn)存在明显的差异,Ⅰ型绿帘石贫Fe、Mn,富Al元素,具有相对较低的XFe值,Ⅱ型绿帘石与之相反,富Fe、Mn,贫Al元素,具有相对较高的XFe值.结合矿相学特征,文章提出Ⅰ型绿帘石由斜长石蚀变而成,Ⅱ型绿帘石由角闪石蚀变而成,暗示绿帘石的主量元素变化受蚀变前的矿物控制.LA-ICP-MS分析测试结果表明,青磐岩化带中由深部至浅部Ⅱ型绿帘石的w(Pb)、w( Sb)、w(Ba)显示升高的趋势,浅部绿帘石具有较低的w(Mo);Ⅱ型绿帘石中的w(Mn)、n(Al)和w(Mg)随着深度的增加呈现出先升高后降低的变化趋势,w(As)、n(Fe)和n(Ca)呈现出相反的空间变化趋势.由于绿帘石的微量元素找矿指标变化受温度等物理化学条件的影响,根据Čukaru Peki铜金矿床绿帘石中的w(Mg)、w(Pb)、w(Sb)、w(Ba)、w( Mo)、w(Mn)、w(As)的空间变化规律,笔者推测该斑岩型矿床热液中心在Mn元素晕之下1～2 km处.笔者研究发现Ⅱ型绿帘石中的主量元素n(Al)和XFe与w(Mn)微量元素呈现类似的变化趋势,n(Ca)和n(Fe)与w(Mn)呈现相反的变化趋势,故Ⅱ型绿帘石中的n(Al)、XFe、n(Ca)和n(Fe)元素可以作为找矿勘查的新指标.

Abstract ：
The Hebaoshan gold deposit (41.5 t Au @ 3.5 g/t) is located in the southeastern region of the South China Block, central part of the Wuyishan metallogenic belt. The ore-hosting rocks in this area are predominantly Precambrian metasedimentary rocks and Caledonian granitic rocks. Two hydrothermal mineralization stages can be distinguished: a quartz-sericite-pyrite-native gold (stage I) and a chlorite-quartz-sericite-chalcopyrite-electrum (stage II), with hydrothermal monazite and rutile are firstly identified in separate stages. The complex geological history of the region has resulted in ongoing debates regarding the age of gold mineralization and the genesis of the major gold deposits in this area. In order to precisely constrain the mineralization age of the deposit and further establish a genetic model for the ore deposit, LA-ICP-MS U-Pb dating and trace element analysis on accessory minerals were conducted. Based on the textures mineral assemblages, and geochemical features of the accessory minerals, magmatic apatite, hydrothermal rutile, and both magmatic and hydrothermal monazite were identified. The U-Pb ages of magmatic apatite and monazite are determined to be 445.3 f 15.80, 441.3 f 15.10 Ma and 446.57 f 1.03 Ma, respectively, suggesting that these ages represent the emplacement ages of the Caledonian intrusive rocks. The ages of hydrothermal monazite and hydrothermal rutile are determined to be 238.46 f 2.01 Ma (single-mineral analysis), 238.46 f 2.01 Ma (in-suit analysis) and 179.54 f 7.28 Ma, respectively, suggesting that represent two mineralization events during the Late Triassic to early Jurassic in the Hebaoshan area. These data provide new constraints on the mineralization process in the Hebaoshan deposit and excludes the link between gold mineralization and the intrusion of the Caledonian granites. Regionally, It is speculated that the two mineralization events at Hebaoshan are respectively associated with intracontinental orogenic movements between the Yangtze Block and Cathaysia Block, the flat-slab subduction of the PaleoPacific Plate (stage I), and the subsequent extensional tectonics related to the collision between the Yangtze Block and Cathaysia Block (stage II). Our study indicates that the timing of multiple episodic mineralization can be constrained by analysis of accessory minerals, which provides a geological basis for better genetic model for the deposit and provide geological evidence for unraveling the relationships between magmatic activities and mineralization events in the region.
