The main successive strategic bases of resources for Pb-Zn deposits in China

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.
