摘要
利用应力扰乱现象、微断裂擦痕、断层岩和变形标志物等进行应力及应变分析的结果表明:灌阳地区沉积盖层构造主要经历了印支构造运动阶段和燕山构造运动阶段,前者以褶皱构造作用为主,形成南北向灌阳复式向斜及其构造组合;后者以断裂构造作用为主,形成北东向大型走滑断层。
The results of stress and strain analysis on structure of sedimentarycover by stress disturbances, microfault slickenside, fault rocks and defor-mation marks show that Indo-China and Yanshanian movements mainlytook place in Guanyang. The former was mainly folding and formed theSouth-North Guanyang synclinorium, the latter was mainly faulting andformed North-East strike-slip faults.
