The Hutouya Pb–Zn mining district in the Qiman Tagh region in NW China is a zoned skarn district with inner Fe–Sn–Cu–Co ores and outer Pb–Zn skarn mineralization. Temporal coincidence of ⁴⁰Ar/³⁹Ar plateau age of ore-stage phlogopite (226.9 ± 1.5 Ma) with weighted mean LA–ICP–MS U–Pb ages of zircons (230.3 ± 3.7 and 221.6 ± 1.3 Ma) and ⁴⁰Ar/³⁹Ar pla...
The Weibao copper–lead–zinc skarn deposit is located in the northern East Kunlun terrane, NW China. Igneous intrusions in this deposit consist of barren diorite porphyry (U–Pb zircon age of 232.0 ± 2.0 Ma) and ore-bearing quartz diorite and pyroxene diorite (U–Pb zircon ages of 223.3 ± 1.5 and 224.6 ± 2.9 Ma, respectively). Whole-rock major and tra...
Mineral inclusions, e.g., apatite, titanite, monazite, K-feldspar, are common in magmatic zircons. Although many studies mention that light rare earth element (LREE) contents of zircons could be compromised by an analytical artefact of the accidental sampling of mineral inclusions, how and to what degree these inclusions influence analysis of zirco...
The East Kunlun Orogen (EKO), as the west segment of the Central China Orogen, is the most important Triassic polymetallic metallogenic belt in China. In this paper, we summarize the geological characteristics (stratigraphy, structure, ore-related plutons, wall rock alteration, and orebodies), ore-forming fluids and materials, geochronology, and pe...
The Weibao Cu-Pb-Zn deposit is typical of skarn deposits in the Qimantagh metallogenic belt (QMB), East Kunlun Mountains, northern Tibetan Plateau. It comprises three ore blocks from west to east, known as Weixi, Main and Weidong. Mineralization in the Weibao deposit is intimately related to Late Triassic intrusions occurring at Weixi and Weidong,...
The Weibao copper–lead–zinc deposit, located in the eastern part of the Qimantagh area, East Kunlun Orogenic Belt (EKOB), consists of three skarn ore blocks known as Weixi, Main and Weidong from west to east. The mineralization within the Weibao Cu–Pb–Zn deposit is hosted by the Mesoproterozoic Langyashan Formation. In this study, we describe for t...
The Baiganhu W–Sn orefield in the southeastern Xinjiang Uygur Autonomous Region is associated with Caledonian S-type syenogranites and metasediments of the Paleoproterozoic Jinshuikou Group. Four types of garnets have been identified in the orefield using petrographic and major and trace element data. Grt-I garnets are generally present as inclusio...
The newly discovered large-scale Baiganhu W–Sn orefield, consisting of the Kekekaerde, Baiganhu, Bashierxi, and Awaer deposits, is located in Ruoqiang County, southeastern Xinjiang, China. These deposits comprise mainly three types of W–Sn mineralization: early-stage skarn-type, middle-stage greisen-type, and late-stage quartz-vein-type. In this st...
The Saishitang Cu deposit, located on the eastern area of the Eastern Kunlun Orogenic Belt (EKOB), and on the northern margin of the Tibetan Plateau, is one of the most important copper deposits in Qinghai Province, China. Skarn and Cu orebodies mainly occur as stratoids or lenses along the contact zone between the quartz diorite and Lower to Middl...
The metamorphosed sedimentary type of iron deposits (BIF) is the most important type of iron deposits in the world, and super-large iron ore clusters of this type include the Quadrilatero Ferrifero district and Carajas in Brazil, Hamersley in Australia, Kursk in Russia, Central Province of India and Anshan-Benxi in China. Subordinated types of iron...
The Yinkeng orefield in Yudu County, Jiangxi Province, SE China, is a zone of concentrated Au-Ag-Pb-Zn-Cu-Mn polymetallic ores. Based on summing up basic geology and ore geology of the orefield, the polymetallic deposits in the orefield have been divided into seven major substyles according to their occurring positions and control factors. The ore-...
The southern Jiangxi Province is a major part of the Nanling W–Sn metallogenic province of southern China, where all W–Sn ore deposits are temporally and spatially related to Mesozoic granitic intrusions. The Tianmenshan–Hongtaoling orefield is a recently explored territory endowed by several styles of W–Sn mineralization. The orefield comprises th...
The Tuolugou cobalt–(gold) deposit, in the northeastern margin of the Qinghai–Tibetan plateau and central part of the eastern Kunlun orogenic belt, is the most recently discovered, large, cobalt–(gold) discovery in Qinghai Province, NW China. Exploration to date has identified a cobalt resource of greater than 20,000 t Co, with significant potentia...

... The REE patterns (Fig. 6c) show either (i) low LREE and MREE (Yb/La) N > 1500; (Yb/Sm) N > 300 and a weak Ce anomaly, similar to some spectra of Type II zircon, or (ii) notably higher LREE and MREE concentrations sometimes exceeding HREE, and no Ce anomaly. As it was reported (Zhong et al., 2018), even a minor percentage (0.05%) of a REE phase falling under the beam can bias REE patterns to orders of magnitude greater LREE enrichment. Therefore, the high-LREE and high-MREE patterns of Type III zircon may rather represent inclusions of REE phases mixed in different proportions. ...

... Paleo-Tethys from oceanic slab subduction to continental collision in EKOB, which is also an important polymetallic belt, remains to be discussed [2]. The porphyry and skarn deposits in EKOB occur mostly in Triassic granites ( Figure 1B), such as the Yazigou, Hutouya, Saishitang, Yemaquan, Wulanwuzhuer, and Jiadanggen deposits [1,13]. ...
... As hydrothermal activities and mineralization in porphyry-skarn systems are intimately tied to the emplacement of ore-forming intrusions (Razique et al. 2014), the associated hydrothermal and mineralization events at Hutouya probably have similar short durations of just a few million years or less (Zhong et al., 2018). At the regional scale, magmatism at Hutouya coincides with that in the other porphyry and skarn deposits in the QMB (Fig. 1C). ...
... Lead isotope compositions (particularly those of sulfide minerals, such as pyrite and galena) are an excellent proxy for constraining the sources of lead in ore-forming fluids [53,54]. Lead isotopes can fingerprint metal sources, reveal the nature of Pb reservoirs, and determine rough tectonic settings for ore formation [55,56]. ...

The Qimantagh metallogenic belt (QMB) is a significant Fe-Pb-Zn-Cu (-Ag) mineral belt that extends for 550 km in the East Kunlun Mountains, on the northern Tibetan Plateau (Figure 1a; [1][2][3][4][5][6][7]). Skarn deposits in the QMB can be subdivided into several main types based on the dominant metal. ...
... Finally, there is the large, newly discovered Baiganhu W -Sn deposit in the Eastern Kunlun Orogen with a reserve of 0.18 million tonnes of WO 3 Zhou et al., 2016Zhou et al., , 2017. This deposit is related to a highly evolved Paleozoic granitic magma that intruded into metamorphosed clastic and carbonate rocks of Paleoproterozoic age. ...

... In the Northern Qimantagh Belt, the Late Triassic granitoids are composed of granodiorite, monzogranite, and syenogranite with an intrusion time of 225-216 Ma (Qi 2015;Zhang et al. 2016;Yin et al. 2017;Xu et al. 2019). The Late Triassic granitoids are widely distributed in the Central Kunlun Belt, and the plutons contain a wide range of compositions from quartz diorite to granite with emplacement ages of 229-216 Ma (Chen et al. 2013aXia et al. 2014;Xiong et al. 2014;Wang et al. 2016;Zhou et al. 2020). Moreover, there are mafic dikes with a younger age range of 218-215 Ma in the Wulonggou and Zongjia areas of the Central Kunlun Belt (Ding et al. 2014;Xiong 2014). ...
... To combat the problem, numerous iron and steel companies opt to utilize low-grade ore in large quantities and supplement it with a significant amount of ferrous metallurgical solid waste in the raw materials [1,2]. Iron-bearing low-grade ores and metallurgical wastes are known for containing high levels of harmful elements, including alkali metals such as K and Na, which will increase the alkali loads on blast furnaces [3,4]. Additionally, alkali metals are cyclically enriched in the form of alkali vapor within the blast furnace [5,6]. ...
