深大断裂对松辽断陷盆地群南部的控制作用
|
摘要
通过野外地质调查及对各断陷典型地震剖面和构造发育史剖面的综合研究,系统探讨了研究区深大断裂对断陷盆地群的控制作用。以西拉木伦河-长春-延吉板块拼接带、赤峰-开原超岩石圈断裂为边界,将研究区自南向北分为辽西盆地区、辽北盆地区和吉西盆地区等3个一级构造分区;根据控盆断裂及其断陷盆地群的时空分布、断陷构造样式、不同时期伸展量等特征将辽北盆地区分为西部、中西部、中东部等3个二级断陷区。西拉木伦河断裂控制了西部区断陷的形成和分布;嫩江—八里罕断裂和孙吴—大庆—阜新断裂对中西部断陷区的控盆效应大体相近;孙吴—大庆—阜新断裂与佳木斯—伊通断裂共同对中东部断陷区起着重要的控制作用;昌图断陷主要受佳木斯—伊通断裂所控制。辽北盆地区主要表现为双断式地堑,断陷群的形成和分布不仅受北北东向断裂控制,也受到近东西向的西拉木伦河断裂和赤峰—开原断裂重新活动的控制。中西部断陷区伸展率具有从九佛堂组沉积期—沙海组沉积期—阜新组沉积期依次减小的变化规律。中东部断陷区与中西部断陷区存在明显差异,NNE向与近EW向深大断裂对两区构造分区控制程度不同。
By the field geological survey and comprehensive study of typical seismic and structural history profiles,the authors systematically discussed on the control of deep-large fault to fault basin group.The target region is divided into three first-class tectonic regions from south to north,including western Liaoning basin,northern Liaoning basin and western Jilin basin by the Xilamulunhe—Changchun—Yanji suture belt and the translithospheric fracture in Chifeng—Kaiyuan.The northern Liaoning basin is divided into three second-class fault depression regions,including west,mid—west and mid—east regions based on the basin-control fault,the spatial and temporal distribution of the fault basin group,the structure type of fault depression and the stretching quantity in different periods.The formation and distribution of western fault depression was controlled by Xilamulunhe fault.The effect of controlling basin between Nenjiang—Balihan and Sunwu—Daqing—Fuxin faults to the fault depression in mid—west was relatively same.Both the Sunwu—Daqing—Fuxin and Jiamusi—Yitong faults performed a very important controlling function to the mid—east fault depression region.Changtu fault depression was mainly controlled by Jiamusi—Yitong fault.The northern Liaoning basin region,as a graben,has the fault depression group not only controlled by the fault in NNE direction but also by the re-movement of Xilamulunhe fault and Chifeng—Kaiyuan fault in near EW direction.The stretch rate of fault depression region in the mid—west diminished gradually from the deposit period of Jiufetang Group to Shahai Group and then to Fuxin Group.There was a great difference between the mid—east and mid—west fault depression regions,which was caused by the deep-large faults in NNE and near EW directions in different control degree.
