| 摘 要： | 本文在概述苏浙沪及邻区海陆地壳结构等研究成果的基础上,利用重力资料及其延拓处理反演该区深部构造轮廓,推断了深断裂的分布和类型;探讨了深部地质构造的特征、区划及其与本区地震活动性的关系,如震源深度的分布,地震分布的区域性和成带性。利用重力均衡理论探讨了茅山地区、郯庐断裂带、南黄海、杭嘉湖等区域的重力均衡状态和构造活动性的关系,从深部构造角度分析了浙江核电站邻近区域地质的稳定性和建厂的可行性。

THE RELATION BETWEEN SEISMIC ACTIVITIES AND DEEP STRUCTURES IN JIANGSU ZHEJIANG AND SHANGHAI AND THEIR NEIBOURING AREA |
| |
| Abstract: | Based on the general statement of crust structure of the studied area, combined with the gravity data and their continuation,this paper presents the feature of deep structure as well as its relation to the seismic acti- vities,the distribution and types of deep fractures,the distribution of epicenter depths,and the regional zoning of earthquakes .Using the theory of gravity isostasy,the paper discusses the relatioh between gravity isost- atic states and tectonic activities in areas of Maoshan,Tanlu Fault, southern Yellow Sea,and Hangjiahu Plain.The stability of regional geology and the feasibility of a nuclear power Plant site is also provided from the point of deep structure. |
