摘要
围绕着长江三峡库首区狮子口NNW向线性影像带的构造属性及其地壳稳定性评价问题进行了构造专题研究。以区域地质调查为基础,运用构造解析方法,采用多学科、多手段的综合研究,确认该影像带影像特征最明显的地段乃是一个滑褶型多层式重力滑动构造。本文还分析了该系统形成的介质条件、斜坡构造及动力环境。
A study has been made about the structural attribute of the NNW-trending Shizikou linear image belt in the head area reservoir of the Yangtze River Gorges and the evaluation of its crustal stability. On the basis of regional geological surveys and applying the structural analysis by multi-disciplinary study and multiple methods, it has been confirmed that the segment with the best displayed image characteristics is marked by a gravity gliding structure with a multilayered gliding fold type architecture. This paper also analyzes the medium conditions, slope structure and dynamic environment for the formation of the structure system.
