| 英文摘要 | The Qingchengzi ore filed in the Liaodong Peninsula is a polymetallic ore field, including 15 Pb-Zn deposits, 3 Ag deposits, and 17 Au deposits. The mineralization is closely related to the Mesozoic magmatism. Among those deposits, two styles of vein mineralization, namely, Pb-Zn and Ag mineralization are developed in the ore field which has reserves of 1.5 Mt of Pb + Zn, 2000 t of silver, respectively. It is still unclear whether the two styles of mineralization are related, while the knowledge carries fundamental importance to understand the mineralization events at a regional scale. To address this, we selected the Xinling Ag-Pb-Zn deposit as a case study, which demonstrates excellent two independent Pb-Zn and Ag mineralization events, but at a single deposit scale. Detailed mineralogy characterization was carried out, along with in situ geochemical and S-Pb isotope analysis of the sulfides from the two styles of mineralization. The Pb-Zn mineralization comprises 0.5?4.5 m wide veins of sphalerite-galena-pyrite which extend along strike for 20?100 m, whereas the Ag mineralization consists of 1.0?4.0 m wide veins of quartz-Ag bearing tennantite series -hessite (minor sphalerite, galena, chalcocite) which extend along strike for 30?110 m. The mineral assemblages and trace elements of sulfides indicate a Pb, Zn, and Fe-rich ore-forming fluid and a Cu, Sb, As, Ag, and Te-rich fluid. LA-ICP-MS mapping and data processing by a software package XMaptools highlight trace element remobilization of primary sphalerite as a result of the overprinting event. Sphalerite geothermometer indicates that Pb-Zn veins formed at medium temperatures (251?273 ?C), whereas the Ag mineralization precipitated at low temperatures (185?246 ?C). Sulfides from the Pb-Zn and Ag ore bodies have ?34S values ranging from 4.94 to 6.35%o and 4.99 to 6.36%o, respectively, indicating that the sulfur may be derived from magmatic fluids. In situ Pb isotope analysis of sulfides reveals very different Pb isotopic ratios in Pb-Zn mineralization (lying on the Pb evolution curve of crust: ? = 9.74) when compared to the Ag mineralization (lying on the lower curve with ? = 9.5), suggesting they may form from distinct magmatic-hydrothermal systems. The observation and dataset suggest that the Pb-Zn maybe medium temperature carbonate-replacement mineralization and was overprinted by later epithermal Ag mineralization. |
