Abstract

Caijiaying PbZnAg deposit is typically controlled by geological structure. The regional oreguided structures are characterized by multistage movement. The early tensional process of the structures constrained the distribution of magmatic rocks in the area;the late compressiveshear process formed plume structures arranged in parallel beside the regional structures,which provided a proper space for location of thermal fluid and formation of PbZnAg deposit.Consistence between isotopic model age of lead ore and intrusion age of quartz porphyry shows close relations among structure movements,magmatism and mineralization in Stage of Yenshan.
