摘　　要：大瑶山 -西大明山是广西主要的金银产地和重要的成矿远景区 .区内金银矿床主要产于寒武系中 .矿床形成与加里东和燕山期构造活动和岩浆作用密切相关 ,形成与同熔型花岗岩类有关的Au -Ag -Cu成矿系列 ,并建立了挤压构造条件下的岩浆 -热液成矿系统 .In Dayaoshan Xidamingshan area, both the main gold silver mining region and the important mineral prospecting region in Guangxi, the gold silver deposits are mainly situated in the Cambrian strata. The Au Ag mineralization was closely related to the tectonic activity and magmatism in the Caledonian and Yanshanian movements, resulting in the Au Ag Cu metallogenic series related to the syntectic/compressive granite. In this way, the magmatic and hydrothermal ore forming system was established on the extrusive structure in this area.
