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 :
Sulphosalt assemblages in a specimen from the Boliden Au-Cu-(As) deposit (northern Sweden) comprise micron- to nanoscale intergrowths of Se-rich izoklakeite and tintinaite with average formulae and calculated homologue number (N) given as: (Cu1.88Fe0.18)2.06(Pb22.92Ag1.47Cd0.01Zn0.01)24.41(Sb13.12Bi8.69)21.8(S50.19Se6.43Te0.12)56.73, N=3.83, and (Cu1.31Fe0.74)2.05(Pb10.58Ag0.18Cd0.05Zn0.02)10.83(Sb10.2Bi5.23)15.43(S32.22Se2.46)34.7, N=2.05, respectively. Tintinaite coexists with (Bi, Se)-rich jamesonite. High-angle annular dark field scanning transmission electron microscopy (HAADF STEM) imaging reveals chessboard structures comprising PbS and SnS modules with the number of atoms in the octahedral (M) sites counted as: n1=18 and n2=8 for tintinaite, and n1=30 and n2=16 for izoklakeite. Homologue number can be calculated using the formula: N=(n1/6)-1 and N=n2/4 for PbS and SnS modules giving NTti=2 and NIz=4. A new N=3 homologue, defined by n=12 and n=24 SnS and PbS modules, respectively, is identified as single or double units within areas with intergrowths between kobellite and izoklakeite. HAADF STEM imaging also reveals features attributable to lone electron pair micelles within the Sb-rich kobellite homologues. Atomic-resolution EDS STEM chemical mapping of Pb-Bi-Sb-sulphosalts shows a correlation with crystal structural modularity. The maps also highlight sites in the SnS modules of tintinaite in which Sb>Bi. Coherent nanoscale intergrowths between tintinaite and izoklakeite define jigsaw patterns evolving from chessboard structures and are considered to have formed during cocrystallisation of the two phases. Displacement textures and crosscutting veinlets (a few nm in width) are interpreted as evidence for superimposed syn-metamorphic deformation and are associated with the redistribution of Bi and Se. Imaging and mapping using HAADF STEM techniques is well suited to characterisation of Pb-Sb-Bi-sulphosalt phases, offering largely untapped potential to unravel the evolution of chessboard structures with applications across mineralogy but also extending into allied fields. © 2024 Cambridge University Press.

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 ± 15.80, 441.3 ± 15.10 Ma and 446.57 ± 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 ± 2.01 Ma (single-mineral analysis), 238.46 ± 2.01 Ma (in-suit analysis) and 179.54 ± 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 Paleo-Pacific 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. © 2024

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, U.K. The mineral and name have been approved by the IMA Commission on New Minerals and Mineral Nomenclature (proposal 2023-062). The aleksite series is an accretional homologous series in which each member is derived from the same 5-atom tetradymite archetype. Clogauite crystallizes in the trigonal crystal system (space group: P-3m1, # 164). Three distinct polytypes of clogauite are recognized, 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) Å, c = 23.46(14) Å, V = 371.598 Å3, Z = 1; clogauite-24H, a = 4.278(4) Å, c = 46.88(31) Å, V = 743.053 Å3, Z = 2; and clogauite-36H, a = 4.278(4) Å, c = 70.36(32) Å, V = 1115.283 Å3, 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 was 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 file (cif) data files. STEM and electron diffraction simulations based on the crystallographic information data obtained from the DFT calculations show an excellent match to the empirical measurements. © 2024 Cambridge University Press.

Abstract :
The Zijinshan ore field is situated in the southeastern part of China. in which contains the large Zijinshan highsulfidation Cu-Au deposit, the Luoboling porphyry Cu-Mo deposit, the Yueyang low-sulfidation Au-Ag deposit, the Longjiangting and the Wuziqilong tansitional Cu deposit, and the Xi'nan porphyry Cu-Mo prospect. Debates on genetic relationship among these deposits, especially the relationship between the Zijinshan Cu-Au deposit and the adjacent Luoboling deposit is a question of importance for further exploration in this ore field. In this contribution, the alteration mineralogy, alteration texture, zonation and mineral chemistry, in combination with shortwave infrared spectroscopy (SWIR) analysis of white mica were used to help focus exploration and assessment of hydrothermal deposits in the Zijinshan ore field. In this study, diaspore-pyrophyllite alteration zone, chlorite-sericite alteration zone and propylitic alteration zone were first identified in the deep drill core of the Zijinshan Cu-Au deposit, which gives way upward to quartzalunite-kaolinite zone, quartz-alunite zone and the silicic alteration zone. In the Xi'nan Cu-Mo prospect, diaspore-pyrophyllite alteration zone was first recognized in the shallow level with the chlorite-sericite alteration zone and propylitic alteration zone in the deeper level. Andalusite- sericite +/- diaspore alteration zone was first recognized in the upper part of the Luoboling Cu-Mo deposit and the deeper part of the Wuziqilong Cu deposit. It indicates that a pervasive occurrence of diaspore-pyrophyllite +/- andalusite alteration zones in the Zijinshan ore field, which may potentially represent a transitional environment between the top of porphyry alteration zones and the base of advanced argillic alteration zones. Minerals of the white mica group are extensively distributed in various alteration zones of the Zijinshan ore field. The SWIR analysis of white mica indicated that the wavelength position of the Al-OH (similar to 2,200 nm; wAlOH) absorption feature increases gradually from the shallow kaolinitedickite alteration zone to the deep potassic alteration zone. In the advanced argillic alteration zones, the range of wAlOH values of white mica is less than 2205 nm. Conversely, in the porphyry alteration zones, it always exceeds 2205 nm. It is evident that the andalusite-sericite alteration zone with higher wAlOH values (average of 2203 nm) is always proximal to the porphyry mineralization, which may act as indicators for deep porphyry prospecting. The results of electron probe microanalysis (EPMA) reveal that the early enrichment of Mg and depletion of Fe in white mica can be attributed to the preferential incorporation of Fe into iron oxides and iron sulfides in the potassic and propylitic alteration zones. Overall, there is a negative correlation between wAlOH and Al, while wAlOH exhibits a positive correlation with the sum of Fe + Mg + Mn. The distribution characteristics of alteration zones and the variation patterns of the wAlOH of white mica indicate that there are probably several paleo-thermal centers in the deep parts of the Zijinshan ore field, located respectively in the deep parts of the Xi'nan Cu-Mo prospect and the deep part of the Zijinshan Cu-Au deposit and the deep parts of the Wuziqilong Cu deposit, and the latest seems to be more fertile and deserves further exploration.

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 :
The Tethys metallogenic belt is one of the three major metallogenic belts in the world. Porphyry deposits, epithermal deposits and skarn deposits are widely developed in this belt. The ABTS metallogenic belt is composed of Apuseni-Banat, Timok and Srednogorie ore concentration in the western part of the Tethys metallogenic belt. The mineralization is mainly related to calc-alkaline magmatic activity in the Late Cretaceous. Timok ore field is one of the ore fields with great economic significance in the ABTS metallogenic belt. It is of great significance to summarize the geological characteristics and metallogenic regularity of the deposit in this area for prospecting and exploration. Based on an overview of the geological characteristics of typical deposits in the Timok ore field, the metallogenic regularity and dynamic background of the ore field are discussed in this paper. The results show that the typical ore deposit in Timok ore field was formed between 88 Ma and 78 Ma, and the mineralization lasted only about 10 Ma. The mineralization age in Timok ore field also shows a trend of becoming younger from east to west. The typical deposit types in the ore field are mainly porphyry deposits (such as Majdanpek deposit, Veliki Krivelj deposit and Valja Strz deposit) and high sulfidation epithermal-porphyry deposits (such as Bor deposit and Cukaru Peki deposit), which are mainly Cu-Au mineralization. The differences in deposit types, mineralization characteristics and burial depth of ore bodies are caused by thrusting nappe structure and uneven denudation after mineralization. At the same time, the mineralization types of typical deposits and the change trend of depth of ore bodies in the ore field indicate that there are still great prospecting potential in the north-northwest of the ore field, the southeast of the Cukaru Peki deposit. © 2024 China Geological Survey.

Abstract :
特提斯成矿带是全球三大成矿带之一,阿普塞尼(Apuseni)-巴纳特(Banat)-蒂莫克(Timok)-斯雷德诺戈里斯基(Srednogorie)岩浆成矿带(ABTS多金属成矿带)位于特提斯成矿带西缘,由阿普塞尼–巴纳特铁铜铅锌矿集区、蒂莫克铜金矿集区和斯雷德诺戈里斯基铜金矿集区组成,成矿作用主要与晚白垩世钙碱性岩浆活动有关。塞尔维亚蒂莫克铜金矿集区作为ABTS多金属成矿带经济意义巨大的矿集区之一,总结该地区矿床地质特征及成矿规律对下一步的找矿勘查具有重要指导意义。综述了蒂莫克铜金矿集区及其典型矿床的地质特征,总结了矿集区成矿规律与动力学背景。蒂莫克铜金矿集区典型矿床形成时代集中在88~78 Ma之间,成矿作用历时10 Ma左右,矿集区内成矿作用时代呈现出由东向西逐渐年轻的趋势。矿集区中典型矿床类型主要为斑岩型(如马伊丹佩克矿床、克里韦利矿床和瓦利亚斯特尔茨矿床)和高硫化浅成低温热液-斑岩型(如博尔矿床和丘卡卢佩吉矿床),这些矿床以铜金矿化为主。矿床类型、矿化特征及矿体埋深存在的差异可能与区域上新生代右旋构造在矿集区形成的逆冲推覆构造及成矿后不均匀剥蚀有关。根据矿集区典型矿床的矿化类型及矿体埋深海拔标高的变化趋势,认为矿集区北部—西北部和丘卡卢佩吉矿床东南部仍具有一定的找矿潜力。
