Geological and isotopic evidence for magmatic-hydrothermal origin of the Ag–Pb–Zn deposits in the Lengshuikeng District, east-central China

Genesis of Pb–Zn Mineralization Beneath the Xiangshan Uranium Orefield, South China: Constraints from H–O–S–Pb Isotopes and Rb–Sr Dating

“…Considering the close spatial–temporal relations of the Mesozoic volcanic host rocks with the mineralization at Xiangshan, we propose that the sulfur may have been mainly derived from these volcanic rocks and to a lesser extent from the metamorphic basement. The Xiangshan data are similar to those of many epithermal Pb–Zn deposits in the region, for example, Huangbi (2.5–5.1‰; Zhang et al, ), Lengshuikeng (−3.8‰ to 6.9‰; Wang et al, ), and Caijiaping (−1.1‰ to 2.5‰; Dai et al, ) (Fig. ), whose sulfur is also interpreted to be derived mainly from the volcanic/subvolcanic host rocks.…”

Early Cretaceous adakitic granitoids from the Zhijiazhuang skarn iron deposit, North Taihang Mountain, China: Implications for petrogenesis and metallogenesis associated with craton destruction

“…The Zhijiazhuang skarn iron deposit is located at the south‐western domain of the Wanganzhen pluton and at the centre of the Laiyuan Complex (Figures b and ), where strip mining has been going on for more than 40 years (Zhu et al, ; Figure a,b). The strata exposed in the deposit mainly comprise carbonate sequence represented dominantly by dolomite belonging to the Proterozoic Gaoyuzhuang and Wumishan formations, gneissic rocks belonging to the Archean Wutai and Fuping complexes in the east and west, and minor Mesozoic volcanic rocks to the south (Ma, ; Wang, Sun, et al, ; Zhu et al, ; Figure ). The dolomites from the Gaoyuzhuang Formation are medium thickness‐layered dolomite and chert‐banded dolomite (Figure ).…”

“…Deep faults (F1, F3) are regional ore‐controlling faults (Figure ), and the contact zone between the biotite granite intrusion and Proterozoic dolomite is considered to be the basic deposit‐scale ore‐controlling zone (Ma, ; Zhu et al, ). The Zhijiazhuang anticline within the west of F1 fault with both flanks containing dolomite of the Gaoyuzhuang Formation is one major ore‐controlling fault of the Zhijiazhuang skarn iron deposit (Ma, ; Zhu et al, ; Wang, Sun, et al, ). The Mesozoic intrusions exposed in the Zhijiazhuang skarn iron deposit mainly consist of a suite of intermediate‐felsic magmatic rocks, including alaskite, granite, biotite granite, diorite, dioritic porphyry, and amphibole monzoporphyry which are characterized by granitic or porphyritic textures, together with Mesozoic extrusive suite within the southern and north‐western domains of this deposit represented by porphyritic andesite and rhyolitic porphyry (Figure ).…”

“…The ore bodies in the Zhijiazhuang skarn iron deposit are lenticular and vein‐type, mainly distributed in the outer contact zone of the skarn, and controlled by contact structure and Zhijiazhuang anticline which is subparallel with the contact zone (Chang & Feng, ; Zhu et al, ; Wang, Sun, et al, ; Figure ). The northern ore block within the northern domain of the Zhijiazhuang anticline forms part of the serpentine skarn belt, and the orebodies in the ore block have a length of 280–380 m and thickness in the range of 10 to 14 m with NNE‐trend and dipping 5–60° (Wang, Sun, et al, ).…”

Mineralization processes at the giant Jinding Zn–Pb deposit, Lanping Basin, Sanjiang Tethys Orogen: Evidence from in situ trace element analysis of pyrite and marcasite

“…Pyrite and marcasite in hydrothermal ore deposits record significant trace concentrations of Cu, Pb, Zn, Au, Ag, Co, Ni, As, Sb, Se, Te, Hg, Tl, and Bi (Cook & Chryssoulis, ; Cook, Ciobanu, et al, ; Deditius et al, , ; Large et al, ; Reich et al, , ; Saini‐Eidukat, Melcher, & Lodziak, ). Pyrite and marcasite have increasingly been regarded as tools for evaluating ore‐forming processes with their trace element signatures used to elucidate depositional processes and deposit genesis, particularly regarding Au mineralization (e.g., Chouinard et al, ; Cook, Ciobanu, et al, ; Cook, Ciobanu, Pring, et al, ; Franchini et al, ; Genna & Gaboury, ; Maydagán, Franchini, Lentz, Pons, & McFarlane, ; Reich et al, ; Wang, Zhang, et al, ; Zwahlen, Cioldi, Wagner, Rey, & Heinrich, ). The only available pyrite and marcasite trace element data for Mississippi Valley‐type (MVT) deposit are from the Wiesloch Zn–Pb–Ag deposit in the Upper Rhinegraben of SW Germany, the San Vicente deposit of Central Peru, and the Hoshbulak and Mayuan Zn–Pb deposits of China (Frontbote & Gorzawski, ; Gao et al, ; Li et al, ; Pfaff, Hildebrandt, Leach, Jacob, & Markl, ).…”
