摘要
本文介绍了利用重磁场及其向上延拓计算资料,分析研究重磁场的空间变化特征。文中结合有关地质资料着重探讨了重磁场特征与断裂构造的关系,然后解释推断出上海及邻近地区的20条断裂带。
The use of gravity, magnetic fields and their upward extending calculated data ate introduced and also the characteristics of the space change in gravity, magnetic fields is analyzed as well in this paper. Moreover, combined with the related geological data, the relationship between the characteristics of gravity, magnetic fields and fault structure is approached emphastically and then, 20 fault zones in hanghai and its adjacent area are illustrated and distinguished by the authors.
