摘　　要：湖北省随州市七尖峰地区伸展构造于印支-燕山期进入强烈活动期,至喜山期定型,形成了多层次、多期次的伸展滑脱剪切系统。区内主要滑动面有三个,主要伸展型滑脱拆离断裂有三条,并具有复杂的构造组合。伸展构造的滑动系可分为上、中、下三个部分。主要伸展型滑脱拆离断裂是区内主要控矿因素,不仅制约着成矿热液及成矿物质的运移,而且为成矿提供了有利的赋矿空间。In Qijianfeng area, Suizhou, Hubei, China, extensional tectonics there reached a violent active phase from Indosinian to Yanshanian and were finalized in Himalayan, formed the multilevel and multiphase extensional decollement - shear system. With a complex tectonic assemblage, there are three principal slip planes and three main extensional decollement - decoupling faults in this area. The slip system of the extensional tectonics can be divided in three parts that are upper part,median part and lower part. As the major ore -control factor,the main extensional decollement - decoupling faults not only controlled the migration of the hydrothermal ore - forming solution and ore - forming materials, but also offered the host spaces.
