| 摘 要： | 青藏高原东北部小峡背斜是一个新生代发展起来的基底卷入型背斜.研究表明背斜的形成经历了三次重要变形,新生代早期由于印度板块与欧亚板块的碰撞(约49～29Ma),造成了西宁盆地顺时针旋转,在此变形中,背斜基底早期发育的北西向断层以及新生断层开始右行斜滑,造成了小峡地区盖层轴向北西向褶皱的形成,基底与盖层的变形类似Trish...

| Abstract: | The Xiaoxia anticline of the northeastern Qinghai-Tibetan Plateau is one basement-involved fold forming during the Cenozoic. This study shows that the formation of the anticline underwent at least three deformation events. Due to the Indo-Eurasian collision in the Early Cenozoic (~49Ma),the Xining basin rotated clockwise. And the early northwest-southeast trending faults developed within the basement and new-born faults started to move right-laterally,which resulted in the development of the northwest-south... |
