The Baiyangping lead-zinc-copper-silver polymetallic deposit in Lanping basin is composed of a few ore veins and can be divided into several ore blocks. Based on an analysis of data available in combination with field geological survey, it can be concluded that the strata in the ore district comprise mainly Mesozoic sedimentary rocks. A comprehensive analysis reveals that there were two mineralization events in the Baiyangping ore district, one responsible for the main copper mineralization between Late Paleocene and early Eocene, the other for main lead and zinc polymetallic mineralization in late Eocene-early Oligocene period. The lead and zinc ore-forming fluids activated early copper element and formed the Pb-Zn-Cu polymetallic assemblage in Fulongchang and Baiyangping ore blocks. The mineralization probably occurred at the stage of short-term stress relaxation after strong extrusion when the wall rocks supplied open space, and ore-forming fluids poured into the space to form ore deposit.
