摘要
通过野外地质调查和收集整理已有的研究资料,对贵阳乌当背斜的成因进行了较为系统的分析。调查研究表明,黔中断裂带是黔中隆起和黔南坳陷的边界断层,整体呈NEE向,乌当背斜分布在黔中断裂带上严格受断裂带控制,轴向与断裂带走向一致。黔中断裂带某些部位具有典型的走滑特征——发辫状构造,旁侧发育的R剪切指示其为左行走滑断层,且具有逆冲性质。
Through field geological survey and collected the existing research materials, for guiyang wu when conducted a systematic analysis of the genesis of anticline.Research shows that the fault zone in guizhou is guizhou uplift and trait of boundary fault depression, NEE to on the whole, wu when anticline distribution in guizhou fault lines strictly controlled by faults, axial is consistent with the strike of the fault zone.Qian in the fault zone parts as the typical strike-slip feature of structure, the shear instructions side development of R as the left-lateral slip fault, and is in the nature of thrust.
