临清地区东部新生代伸展构造特征及盆地伸展模式

THE CENOZOIC EXTENDED BASIN CHARACTER AND MODELS IN THE EAST OF LINQING

通过对临清地区东部各主要断层新生代活动性进行半定量—定量分析后 ,认为它们在不同时期的活动量各不相同 ,而且分段活动的特点十分明显 ,控制了不同时期规模、位置不同的半地堑。根据断层活动的特点 ,认为临清东部地区是分层伸展剪切模式 ,在南部、中部、北部均显示了各具特点的伸展组合模式。而这些不同伸展组合模式是通过北西西向或近东西向横向变换构造带进行调节的。

After analysing the Cenozoic activity of major faults in east of Linqing using quantitative and semi-quantitative methods, the authors consider that the major faults in this area controlled the different scales of half-grabens in different areas and have the obviously sectionalized feature and different active levels in different periods of time. They also consider show that extention-related models present differential characters in different sectors of the faults and are accommodated by NWW or sub-EW trending transcurrent transition structure zones.
