| 中文摘要: |
| 美人沟铅锌矿床位于冀西北山、原过渡区中铅锌多金属成矿带内，研究该地区土壤元素特征对于当地矿产勘查和生态保护意义重大。本文通过开展 1∶1万土壤地球化学测量，分析了区内土壤元素分布特征，圈定了地球化学异常，并结合山地工程查证，讨论了成矿前景。结果表明:区内 Pb和 Zn变异系数分别为 3.16和 2.24，富集系数分别为 3.47和 2.31，呈不均匀分布，在局部存在富集成矿可能。在圈定的 11个综合异常中，Yc1、Yc3、Yc5、Yc6和 Yc8是重点综合异常，且在 Yc1综合异常内发现了 2条铅锌矿体和 2条矿化体。结合成矿地质条件分析，区内找矿前景良好，是寻找中低温热液型铅锌矿的有利地区，在该地区开展大比例尺地质勘查，有望获得进一步找矿突破。 |

| The Meiren Valley lead-zinc deposit is located within the lead-zinc polymetallic metallogenic beltin the mountain-plain transition zone of northwestern Hebei. Studying the characteristics of soil elements in thisarea is of great significance for local mineral exploration and ecological protection. In this paper, a 1∶10,000 scalesoil geochemical survey was carried out to analyze the distribution characteristics of soil elements in the study area,delineate geochemical anomalies, and discuss the metallogenic prospect in combination with mountain engineeringverification. The results show that the coefficients of variation (CV) of Pb and Zn in the area are 3.16 and 2.24, re.spectively, and the enrichment coefficients (EC) are 3.47 and 2.31. Both elements exhibit heterogeneous distribu.tion, indicating the potential for enrichment and mineralization in local areas. Among the 11 delineated comprehen.sive anomalies, Yc1, Yc3, Yc5, Yc6, and Yc8 are key comprehensive anomalies; within the Yc1 comprehensiveanomaly, 2 lead-zinc ore bodies and 2 mineralized bodies have been discovered. Combined with the analysis ofmetallogenic geological conditions, the study area has favorable prospecting potential and is a promising region forexploring mesothermal-epithermal type lead-zinc deposits. Conducting large-scale geological exploration in thisarea is expected to achieve further prospecting breakthroughs. |
