松辽盆地敖古拉—他拉哈断裂带构造演化
Tectonic evolution of Aogula-Talaha fault belt in Songliao Basin, China
摘要
Abstract
The Aogula-Talaha fault belt is a complex fault system developed in the middle and shallow layers in the central depression of Songliao Basin.This fault belt is characterized by complex development background,long evolution history,and involved in superposition of multi-stage structural activity.The study of tectonic evolution shows that the Aogula-Talaha fault belt mainly experienced three stages of deformation.The first stage is extensional stage during the deposition of Shahezi Formation,two NNE deep-seated echelon faults formed as the regional major faults.The second stage is depression stage during the deposition of upper Qingshankou Formation,small faults develop intensively above the T2 reflection layer in this stage,and the distribution and evolution of the small fault belts are obviously controlled by the above-mentioned deep-seated main faults.The thirdstage is shrinking period during the deposition of late Mingshui Formation,the previously formeddeep-seated main faults are reversed and extended upward to form a NNE fault belt,the presentAogula-Talaha fault belt,under the influence of regional strike slip.关键词
