| 摘 要： | 据考察区的晚新生代断裂活动性质和结合地震断层、地震应变带、震源机制、地形变、地壳测深等资料的综合分析,认为本区与华北北部的晚新生代应力场既有一致性,又有本身特点。推论是近邻诸板块相向挤压作用和伴随的深部物质运动而导致地壳上部侧向运动等不同级次作用力复杂叠加的结果。指出它与中生代区域应力场不同

PRELIMINARY STUDY OF LATE CENOZOIC TECTONIC STRESS FIELD IN JIANGSU-SHANDONG-ANHUI REGION |
| |
| Abstract: | Based upon the studies of Late Cenozoic faulting and its related features in connection with the data of seismological observations involving a part of focal mechanism, topographic changes and geophysical explorations of the deep portion of the earth, the principal characteristics of the Late Cenozoic tectonic stress field in the region studied are discussed in this paper. It is suggested that the Himalayan movement together with the underthrusting of the Pacific plate reformed the regional stre |
