在查明歧口凹陷构造空间分布特征基础上,运用现代区域构造演化思想、分析方法将歧口凹陷构造演化划分为6个主要阶段:(1)左行平移剪切阶段;(2)北西向拉张阶段;(3)北西向挤压阶段;(4)近南北向快速拉张阶段;(5)近南北向拉张和热沉降过渡阶段;(6)热沉降阶段.
After finding out the characteristics of spatial tectonic distribution in Qikou Depression,the evolutionary ideas and analytical methods of current regional tectonics are used to divided the tectonic evolution of Qikou Depression into six major stages:(1)strikeshear stage,(2)NW extension stage,(3)NW compression stage,(4)near NS rapid extension stage,(5)the transitional stage of near NS extension and thermal subsidence,and(6)thermal subsidence stage.
