In the prospecting for the Median lead-zinc (silver) ore district. new theory and new methods were adopted, with which the ore district was developed from a local small deposit into a large-sized deposit. The present paper has studied its metallogeny as well as characteristics of its geophysical and geochemical fields. and summarized integrated oreprospecting criteria for Mexian type deposits. including deep tectonic setting, regionaltprognosis and ore district detailed investigation. In addition, the technical series for ore Prospecting are gived.
