| Abstract/Notes | Sphalerite geochemistry provides new evidence for the mineralization mechanism, ore-formation temperature, genetic type, and prospecting direction of the Hua’aobaote Zn-Pb-Ag deposit and the Shuangjianzishan Ag-Pb-Zn deposit in the southern margin of the Great Xing’an Range. Laser ablation inductively coupled plasma mass spectrometry analyses reveal that most sphalerite grains from both deposits display flat, stable time-resolved signal profiles, indicating that the analyzed domains are largely free of mineral inclusions. Occasional fluctuations in Cu and Ag signals suggest minor inclusions of Cu- and Ag-bearing phases. Sphalerite compositions indicate that divalent cations (e.g., Fe, Mn) are incorporated via direct substitution for Zn2+, whereas cations with other valence states are commonly incorporated through coupled substitution mechanisms. Both deposits contain sphalerite enriched in In and Sn, with average Sn contents of 181 ppm (Hua’aobaote) and 245 ppm (Shuangjianzishan), significantly exceeding those of non-Sn-mineralized Zn-Pb deposits (<10 ppm) but comparable to values from Sn-mineralized systems associated with highly fractionated granites. Such enrichment patterns are indicators of concealed Sn-fertile magmatic-hydrothermal systems. The data therefore suggest that the ore-forming intrusions at both deposits underwent significant differentiation and metal enrichment processes similar to those responsible for Sn mineralization. This supports the view that the currently exploited Zn-Pb-Ag ores are the distal metallogenic features of larger magmatic-hydrothermal systems that host deeper, high-temperature mineralization (e.g., Sn) closer to the causative intrusion. Application of previous machine learning classification models to multi-element sphalerite data indicates that Hua’aobaote is predominantly of epithermal type, whereas Shuangjianzishan exhibits characteristics of both skarn and epithermal types. Sphalerite geothermometer yields crystallization temperature of 283–336 °C for Hua’aobaote and 270–366 °C for Shuangjianzishan. The obtained temperatures fall below those generally recorded for proximal skarn systems (>400 °C), yet exceed those characteristics of typical MVT deposits (<200 °C). This indicates that Shuangjianzishan represents a transitional magmatic-hydrothermal system with epithermal affinity. Applying this approach to other Ag-Zn-Pb systems with similar sphalerite trace element signatures may help identify concealed Sn orebodies both within the Great Xing’an Range and in surrounding areas. | ||
