PR Prospecting Criteria for Stratiform Lead-Zinc Mineralization.

A study is made of the syngenetic factors and geochemical features causing the accumulation of ore material. These factors include the geostructural group of factors, the lithological-paleogeographic group, and the magmatic group. The geochemical features considered include the geochemical specialization of the ore-enclosing rocks with regard to lead and zinc, and the correlation between lead and zinc in the ore-enclosing rock masses in regions with concentrated mineralization and the absence of a correlation in areas with dispersed mineralization.
