摘要
本文通过对大背坞金矿的地层、构造、矿化、蚀变及主要矿物特征的研究，初步认为该金矿为三阶段成矿模式，即韧性剪切作用使分散金初步富集阶段，韧性剪切作用使金富集成矿阶段和燕山早期岩浆活动造成金的迭加成矿阶段。
Through a study on the stratigraphy,structure,mineralization,and the features of major minerals in the Dabeiwu gold deposit,theauthor holds that the metallogenic model of gold deposit underwentthree stages,that is,the enrichment stage of the dispersed gold cau-sed by the metallogenic stage of gold enrichment resulted in the bri-ttle shearing as well as the gold superimposed metallogenic stage res-ulted by the early stage of Yanshanian magmatism.
