“…A total of five Zn-Pb orebodies have been discovered in this deposit, with ore body I dominated by zinc-lead sulfide minerals and the others mainly composed of zinc-lead carbonate minerals. The orebodies are mainly stratiform, with dip angles ranging from 3 • to 7 • [26]. The ore-bearing host rocks of the deposit are mainly the Middle Jurassic Longshan Formation, with the second and fourth lithologic sections being the ore-bearing strata of the III and IV ore belts, and I and II ore belts, respectively.…”

“…The main zinc-lead deposits of this metallogenic belt are distributed within the Paleogene to Neogene basins in the Lanping-Simao and Tianshuihai North Qiangtang terranes. The Huoshaoyun Zn-Pb deposit occurs within the Linjitang Basin of the Tianshuaihai North Qiangtang Terrane, bounded by the Altyn fault to the southeast, the Jinsha River fault zone to the north, the Karakorum fault to the southwest, and the Qiaoertianshan fault passing through the basin (Figure 2) [23][24][25][26][27]. The exposed strata in the region consist mainly of Triassic and Jurassic formations, from bottom to top: the Middle Triassic Heweitan Formation, the Upper Triassic Keleqinghe Formation, and the Middle Jurassic Longshan Formation [8].…”

The Huoshaoyun zinc–lead deposit, a giant non-sulfide deposit in Xinjiang, is one of the most significant discoveries of zinc–lead deposit in China and globally in recent years. The deposit is dominated by zinc–lead non-sulfides, with minor occurrences of sulfides such as sphalerite, galena, and pyrite. The non-sulfide minerals include smithsonite, cerussite, anglesite, and Fe-oxide. This study focuses on the mineralogical characteristics of sulfide and non-sulfide ores, as well as the trace element characteristics of sphalerite, smithsonite, and Fe-oxide. Mineralogical analysis reveals that smithsonite is derived from the oxidation of primary sulfide minerals and can be classified into three types that are generated during different stages of supergene oxidation. The three types of smithsonite are formed through replacing the sphalerite and host limestone, as well as directly precipitating in the fissures and vugs. Trace element analysis of sphalerite indicates that it is rich in Cd, Tl, and Ge, but poor in Fe and Mn. The ore-forming temperature, calculated using the GGIMFis geothermometer, is mostly within the range of 100~150 °C. Moreover, the trace element characteristics, ore-forming temperature, and S and Pb isotope compositions of the sulfide ores of the Huoshaoyun deposit are similar to those of the Jinding and Duocaima MVT lead–zinc deposits, which are also located in the Eastern Tethyan zinc–lead belt. This suggests that the sulfide orebody in the Huoshaoyun Zn-Pb deposit could also be the MVT deposit. Study of the trace element of the non-sulfide minerals shows that the Mn and Cd are relatively enriched in smithsonite, while Ga, Ge, and Pb are enriched in Fe-oxide. This can be attributed to distinct geochemical properties of the trace elements in the non-sulfide minerals of the Huoshaoyun deposit and is consistent with those of the other oxidized MVT deposits, thus indicating the supergene oxidation process of this deposit.
