摘要: 提要：铅锌原本是中国的优势资源，但随着国内铅锌资源需求不断增大，中国铅锌的后备资源难以跟上现代化建设的步伐。文章通过总结中国铅锌矿的主要特征，分析中国铅锌资源面临的问题，并根据铅锌资源潜力评价工作需要，将中国铅锌矿床划分为(火山)-沉积变质型、火山岩型海相、火山岩型陆相、矽卡岩型、层控热液型、岩浆热液型、风化（壳）型7类不同的预测类型，共计48个矿床式。基于此，对目前已发现的的潜在铅锌矿集区进行了潜力分析，在全国范围内共划分出28个铅锌资源战略接续区，并对重点接续区进行了介绍。最后通过资源潜力分析，对中国铅锌矿床下一步工作部署提出了一些建议和意见。Abstract: Abstract：To meet the demands for Pb-Zn resources, China should have more lead and zinc resource reserves to keep up with the step of modernization construction. This paper sums up the distribution and characteristics of Pb-Zn deposits in China, and analyzes the problems of enlarging Pb-Zb resource reserves. Then, based on the demand for resource potential, the authors calssified the Pb-Zn deposits in China into 7 prognostic types and 48 models. The 7 types are (volcano)-diagenetic metamorphism type, marine volcanic type, continental volcanic type, skarn type, hydrothermal type, magmatic hydrothermal type and weathering crust type. On such a basis, the discovered ore concentration areas were analyzed for Pb-Zn resource potential, and 28 successive strategic bases for Pb-Zn resources were proposed. The important bases are descrfibed in detail in this paper. Through potential analysis, some suggestions and opinions concerning the further work arrangement are put forward in this paper.
