鲁中地区北西向断裂及其第四纪晚期的活动特征

THE N-W TRENDING FAULTS IN MIDDLE PART OF SHANDONG PROVINCE AND THEIR ACTIVITIES IN THE LATE QUATERNARY

鲁中地区北西向断裂在晚更新世末期曾强烈活动,全新世初期也表现出了一定的活动性.本文在分析北西向断裂基本特征的基础上,着重讨论了北西向断裂晚第四纪活动标志和时代、断层分段活动、活动段的空间分布特点、断裂新活动的力学性质和活动方式等问题.

In the central part of shandong province the N-W trending faults behaved actively abruptly in the late Pleisiocence and moderately in the early Holocence. Based on the analysis on the basic features of the faults, a discussion for the faults is made in this paper with respect to the activity features in the late Quaternary, its segmental activities, the spatial distribution of active segments, the pattern and the mechanical property of its neoactivities.
