| 摘 要： | 本文利用1953—1955年,1976—1980年两期精密水准测量成果编绘的垂直形变图,在苏鲁皖豫地区形变的构造背景作了初步分析。认为区内存在着郯庐带临沂—嘉山段和豫鲁交界两个构造形变异常区。全区形变主要受北西西、北西和北东向断裂控制。郯庐带的现今运动具有明显的分段特征

AN ANALYSIS ON THE GEOTECTONIC BACKGROUND OF VERTICAL DEFORMATION IN THE JIANSU-SHANDONG- ANHUI-HENAN REGION |

| Abstract: | In this paper, a preliminary analysis on the geotectonic background of land deformation has been made using vertical-deformation contour map based on precice levelling that was carried out in 1953-1955 and 1976-1980 in the study region.It is suggested that there are two abnormal areas of deformation, one along the Tancheng-Lujiang fault zone ranging from Linyi to Jiashan; the other at the joint between Shandong and Henan Provinces.For this study region, the deformation is mainly controlled by the faults trending WNW, NW and NE. And recent tectonic movement for the fault zone is of distinct segmentation |
