摘要:
黄陵背斜、秭归向斜是三峡地区构造地质研究热点之一,前人将其划归于秦岭造山带的组成部分,认为是东西向构造后期改造的结果;分布于此区的仙女山断裂是否穿越长江也是争论的焦点问题之一.这些问题的解决对澄清研究区地质灾害分布特征具有重要意义.笔者在前人研究的基础上,从沉积学、构造地质学角度,在大量野外地质研究工作的基础上,提出了新的看法:黄陵背斜、秭归向斜、当阳向斜、仙女山断裂同属统一的构造体系,其形成和演化与中国东西部构造格局的变迁一致,黄陵背斜具有断层相关褶皱的特点,秭归向斜具有前陆挠曲型盆地构造属性;仙女山断裂形成之初具有传递断层的属性,后期又经历了引张、挤压演化过程,不存在跨越长江向北延伸的问题;受秭归向斜沉降幅度以及东西向构造与南北向构造复合影响,在研究区形成3个滑坡聚集区,分别为贾家店滑坡聚集区、八字门向家店滑坡聚集区、兴山县城附近滑坡聚集区.
