摘　　要：论述了大兴安岭成矿带区域构造演化特征.成矿带存在前寒武纪、古生代、中生代3个构造层,各构造层的断裂体系构成了大兴安岭东南段的等距、网格状的构造格局.铜多金属成矿受“带、块、结、点、缘”区域性构造控制.不同型式的构造控制不同成因类型矿床的形成.The southeast section of Daxinganling Mts., covering the east region of Inner Mongolia, is an important component of the Daxinganling metallogenetic belt, which involves three structural layers, i.e. Precambrian layer, Paleozoic layer and Mesozoic layer. The fault systems of the structural layers form the structural framework characterized by equal-interval and rhombus. The regional structures control copper-polymetallic mineralization in zone, block, knot, spot and margin. Different forms of structures result in the forming of various genetic types of deposits.
