CHARACTERISTICS OF CENOZOIC FAULT ACTIVITIES IN THE HUIMIN SUBBASIN

摘要: 通过计算断层活动性参数(生长指数、断层落差和断层活动速率), 优选断层活动速率参数, 分析了凹陷内断裂活动的特征, 划分出四级控凹断层。结果表明, 凹陷内断裂活动具有长期性、差异性和幕式性的复杂特征, 低级次断裂活动具有短期性和不确定性的特点。四级控凹断层分别对凹陷的形成和凹陷内局部构造起着不同的作用。Abstract: The parameters of Quaternary fault activities such as the growth index, fault throw and fault activity rate are calculated to analyze the characteristics of fault activities in the Huimin subbasin and four orders of subbasin-controlling faults are distinguished.The analysis indicates the following:the fault activity rate is the most representative parameter; the fault activities in the Huimin subbasin have the long-continued, differential and episodic characteristics; and the activities of faults of lower orders have the short-term and uncertain characteristics.The subbasin-controlling faults of four orders played different roles in the formation of the subbasin and local structures within the subbasin.
