摘　　要：本文重新研究了二道甸子金矿区的控矿构造，认为控制金矿的二道甸子帚状构造的３条弧形构造带具有３个活动时期：即ＮＷＷ向右旋压扭性断裂活动时期、张扭性帚状构造活动期和压扭性帚状构造活动期，而不同时期、不同性质的活动对金矿均有不同的控制作用，金矿化主要受张扭性帚状构造活动期的控制。矿体总体展布受早期压扭性断裂的限制，而单个矿体则受张扭性帚状构造制约。In this paper,a further study of the structures controlling the Erdaodianzi Golddeposit was conducted.The three arcuaete structural belts that compose the Erdaodianzi brush structure are considered as the major structures that controlled the gold-deposits.The general distribution of the gold deposits was restricted to the early compresso-shear faults and the single ore bodies controlled by the tenso-shear brush structure.
