摘　　要：在介绍茅排韧性剪切带基本特征和含矿性的同时,用"断裂阀—构造泵吸—周期性破裂愈合"的构造—流体耦合成矿动力机制,论述了该剪切带的形成、发育的全过程,并论述了该剪切带构造动力对成矿系统的启动、运行机制和对成矿物质的运动学、几何学特征的控制以及由此产生的成矿过程、聚矿能力和成矿产物之差异。The author introduces the basic feature of ductile shear belt and ore-contained term from Maopai gold deposit. By the fault valve-earthquake pump-cyclically healed framework, the dynamic mechanism of fluid coupled ore-forming term, the procedure of this shear zone＇s forming and mature is explained. Meanwhile, the author discusses this shear belt tectono-dynamics promoting the process of themetallogenic system, handling the operating mechanism, controlling the movement and geometry of the ore-forming substances, and the ore-forming procedure, capacity and the difference.
