Abstract
The orebodies of the Faziba copper deposit in Gansu Province occur in the transitional zone between the metamorphosed intermediate-basic volcanic rocks to sedimentary rocks,with the major ore-bearing bed being copper-bearing magnetite quartzite.Physical characters of various rocks(ores) show remarkable differences.There exists obvious concentration zoning in anomalies of such main ore-forming elements as Cu,Zn,Mo,Co and Au,Ag.Evident geophysical and geochemical anomalies can be observed over the orebodies. Integrated geological-geophysical-geochemical prospecting criteria are put forward in this paper.
