Many Pb-Zn-Ag deposits are found in the middle north margin of North China Block.

Four types of Pb-Zn-Ag deposits occur in the middle north margin of North China Block.

This paper presents an analysis of objective attributes in geology,geochemistry,and geophysics that occur in different sequences of the known mineral deposits,and of the metallogenic geological attributes in the Pb-Zn-Ag deposits in the northem Hebei Province.

Yingfang Pb-Zn-Ag deposit lies in a S-N direction medium ductile shear zone,its mainore body occurs in the contact zone between coarse Or-granite of early Yanshanian andHongqiyingzi Group of Lower Proterozoic.

Shidonggou Pb-Zn-Ag deposit exists within the external contact zone of Yeniutan granodiorite in-trusive,and is controlled by Shidonggou faulted structure.

Sulfur and lead isotopic compositions of lead-zinc-silver deposits in the Gangdise metallogenic belt, Tibet, China, and its geological significance.;

Potash micatization is one of the main hydrothermal alteration minerals genetically related to the lead-zinc-silver deposit.

In recent years, many large-medium scale lead-zinc-silver deposits were found in the southmargin of North China Craton such as Shagou, Lengshuibeigou, Laodaizhanggou and so on.
