摘      要：The region of Northwest Hebei is an area where Au-Ag polymetallic ore depsits are concentrated in Hebei Province. There were divided the Au ore-concentrated region with the magmatic-metamorphic diamictite zone as the center and the perpheral cover-strata zone and Ag-polymetallic metallogenic zone along the line of Xuanhua-Songli-Chicheng. Research on mantle branch structure indicates that Au-Ag polymetallic ore-forming materials come mainly from the deep interior of the Earth. The ore-forming materials tend to migrate upwards through the multi-stage evolution of mantle plume, and are concentrated as ores in the favourable tectonic expansion zone of a mantle branch structure. As viewed in plane, from the center to the periphery and as viewed in space, from the lower part to the upper part there exists Au-Ag-Pb-Zn zonation, as evidenced by drilling data from a number of mines. So, there is still great potential for ore prospecting in the region of Northwest Hebei.
