鲁中地区上五井断裂带的成生和演化

FORM AND EVOLUTION OF SHANGWUJING FAULT IN CENTRAL OF SHANDONG

摘要:

上五井断裂带是郯庐断裂带的派生次级构造，因受主断裂的控制，愈向北（靠近主断裂处）发育越强，愈向南（远离主断裂处）发育越弱。联系郯庐断裂带活动性质，根据构造形迹特征可将上五井断裂带分为４个主要活动期次，它们分别控制了断裂带两侧中、新生代盆地沉积，同时反映了断裂带新构造运动的特征。

Abstract:

Shangwujing fault is the inducedly secondary tectonical of Tancheng-Lujiang faults. Because controlled by the major faults, it developed stronger towards north(near the major faults), while weaker towards south(far away from the major faults). Considering to the movement property of Tancheng-Lujiang faults, Shangwujing fault′s movement can be divided into four active stages, and they differentiated controlled the developements of Mesozoic to Cenozoic basins which distributed along both sides of it.
