| 中文摘要: |
| 本文通过对老虎沟门地区土壤地球化学异常特征进行分析，发现Au、Ag、Pb、Zn是区内的主要成矿元素，而Bi、Sb、Mo等是重要的成矿伴生元素。区内各元素土壤地球化学异常套合较好，结合地质特征圈定了6个综合异常区，综合异常区的展布及异常浓集中心与韧性剪切带、蚀变破碎带、石英脉等密切相关。经工程验证，Ⅰ号综合异常区石英脉内发现两条金矿化体，Ⅳ号综合异常区韧性剪切带内发现金（锌）矿化体、Ⅵ号综合异常区石英脉内发现金矿化体、铅铜矿体，且异常与矿脉套合较好。老虎沟门地区金、银、铅（锌）及其它指示元素土壤地球化学异常规模较大、强度较高，具备良好的成矿地质条件和地球化学环境，具有较大的金、银、铅（锌）等多金属找矿潜力。 |
| 英文摘要: |
| In this paper， the characteristics of soil geochemical anomalies in Huogoumen area are analyzed. It is found that Au， Ag， Pb and Zn are the main ore-forming elements in this area， while Bi， Sb and Mo are the important ore-forming associated elements. The geochemical anomalies of the elements in the area are well integrated， and 6 comprehensive anomaly areas are delineated based on geological characteristics. The distribution and concentration centers of comprehensive anomaly areas are closely related to ductile shear zones， alteration fracture zones and quartz veins. After engineering verification， two gold mineralized bodies were found in the quartz vein of comprehensive anomaly area Ⅰ， gold （zinc） mineralized bodies were found in the ductile shear zone of comprehensive anomaly area Ⅳ， and gold mineralized bodies and lead-copper bodies were found in the quartz vein of comprehensive anomaly area Ⅵ， and the anomalies were well combined with the veins. The soil geochemical anomalies of gold， silver， lead （zinc） and other indicator elements in Huogoumen area are large in scale and high in intensity， with good metallogenic geological conditions and geochemical environment， and have large prospecting potential for gold， silver， lead （zinc） and other polymetals. |
