摘要
本文在简述扬子地台西缘及邻区在大陆演化过程中的主要裂陷事件、裂谷构造类型及演化特点基础上，详细阐述了各类裂谷（陷）构造的主要成矿类型；指出不同的裂谷（陷）构造具有不同的成矿特征；裂谷（陷）构造与深部热地幔上涌相结合是形成攀枝花、东川、呷村、金顶等超大型金属矿床的基本构造条件；伴随扬子大陆的生长，裂谷（陷）成矿作用具有旋回性、阶段性和不可逆性。
Based on the description of the main rift (depression) events in the continental evolution process, rift structuresand their evolutionary features in the western margin of the Yangtzi platform and its neighbouring region, the main metallogenictypes in every rift type are presented. The mineralization is considered to show different characteristics in response to differentrifts. It was under the conditions of combining of rift (depression) with mantle heat up heaving that formed the Panzhihua,Dongchuan, Gacun, Jinding super large-sized ore deposits. The mineralization is characterized by cycles, stages and irreversibilityaccomponied with the growth of the Yangtzi platform.
