| 中文摘要: |
| 贵州赫章猪拱塘铅锌矿床是贵州省内发现的首个中低温热液型超大型铅锌矿床。铅锌矿体严格受北西向断裂构造控制，主要赋存于北西向F1、F2及隐伏F20、F30断裂破碎带及次级断裂破碎带内。根据矿体的空间展布特点，以控容矿断裂作为矿体对比连接的依据，圈定69个铅锌矿体，探明铅锌金属资源量275万吨。Ⅰ-1号主矿体为区内规模最大铅锌矿体，呈似层状、透镜状产出于猪拱塘断层(F1)破碎带内，赋矿围岩建造为二叠系中统栖霞组(P2q)泥灰岩、灰岩、白云质灰岩建造。矿体长度1 640 m，平均厚1101 m，铅平均281%，锌平均871%。铅锌资源量182万吨，占矿床总资源量的 57%，资源量规模达特大型。通过对Ⅰ-1号主矿体地质特征及找矿标志详细论述，为矿床总体特征及成矿规律总结提供依据。 |

| Zhugongtang lead-zinc deposit in Hezhan gis the first medium-low temperature hydrothermal and super-large lead-zinc deposit discovered in Guizhou province. The lead-zinc ore body strictly controlled by the faulted structures in NW mainly occurs in the faulted fracture zones and secondary faulted fracture zones of F1 and F2 in NW, as well as the concealed F20 and F30. According to the spatial characteristics of the ore body, 69 lead-zinc ore bodies were delineated, and 2.75 million tons of lead-zinc metal resources were proven with ore-controlling and ore-hosting structures as the ore bodies for comparison. The main ore body of I-1, formed in the fracture zone of Zhugongtang fault(F1), is the largest lead-zinc ore body in the area, and it appears in bedded and lenticular shapes. The host rocks are composed of marl, limestone, and dolomitic limestone in the Permian Qixia group(P2q). The length and average thickness of the ore body are 1 640 m and 11.01 m respectively, whilethe average lead and zinc levels are 2.81% and 8.71% respectively. The amount of lead and zinc is up to 1.82 million tons, accounting for 57% of the total resources of the deposit. Its proven resources have reached asuper-huge scale. The geological characteristics and of the main ore body of I-1 weredescribed in detail, therefore, this paper can provide an evidence for the overall characteristics and metallogenic regularity of ore deposits. |
