摘要
运用构造解析的原理和方法 ,对在老虎山地区新发现的震旦纪地层的构造叠加、构造置换进行研究 ,划分出 5个构造变形世代。震旦系是一套经历了多期次、多体制、多层次构造变形的古老基底 ,从而为研究北祁连造山带的构造演化提供了重要的依据。
The structural superimposition and transposition of the Sinian strata discovered by the author recently have been studied using the principle and method of the structural analysis, and five generations of structural deformation have been distinguished. It is thought that the Sinian System is old basement that has undergone multi stage, multi system and multi level structural deformation. This structural analysis provided necessary basic data for the study of the structural evolution of the North Qilian orogenic belt.
