摘要

///Based on data of ZK001 borehole in the Heishan Cu-Au deposit, mineralogy, vertical zonation of ore-forming elements has been studied. From the earth’s surface to the deeper, skarn alteration changes from external skarn to inner skarn, and then transits to normal diorite. Based on Gregorian’s zoning index method with barycenter method as a supplement, vertical zoning sequence of ore-forming elements changed from Cu+Sb+Zn+Ag to Au+Ni+As+Co+Zn+Hg+Bi from shallow to deep sites, which is well conformed to the geological fact that Cu ores are located in the shallow parts and Au ores in the deep parts.
