营子街断层研究引发的地质构造问题探讨

Approach to the question of the geological structure found in the research of the Yingzijie fault

结合区域地质背景,研究了营子街断层断面空间几何形态、发育特征与断层幕式活动,发现该断层自深部向浅部、自东向西进行时空迁移演化。基于此,针对走滑断层定义与断层形成机制进行了讨论,指出该断层为临邑断裂带的分支伴生断层,不具有走滑性质,是沙四、沙三段沉积期强烈活动,明化镇组沉积期消亡的同沉积伸展断层。

The spatial geometric shape and development characteristics of the fractured surface and the episodic activities of the Yingzijie fault are researched combined with the background of the areal geology, the results show that the fault migrated and evolved spatially from deep to shallow and from east to west. Based on this, the definition of the strike-slip fault and the mechanism of the fault formation are researched, the conclusion is that the fault is companion fault of the Linyi fracture belt without strike-slip characteristics, is a syndeposit extension fault during intense activity of the depositional stage of Es4 and Es3and the ending of depositional stage of Nm.
