| 摘 要： | 郯庐断裂带是中国东部地球物理场的分界线。它在磁场上呈现出一条NNE向线性正磁异常带,它的重力场特征表现为规模较大的布格重力异常梯度带。在断裂带的两侧,其区域磁场、区域重力场无论是场值大小,还是异常规模以及各异常的展布形态等诸方面都具有明显的区别。地球物理特征揭示郯庐断裂带深部构造,为研究重点矿产分布规律及地震灾害预报具有重要的实际意义。

| Abstract: | TanLu fault belt is the boundary of geophysical field in eastern China.It shows a linear magnetic anomaly zone with the trend of NNE.Its gravitational field is characterized by large scale of Bouguer gravity anomaly belt.In both sides of the fault zone,its regional magnetic field,regional gravity field have obvious differences in scale,abnormal degree and abnormal distribution.Geophysical characteristics of TanLu fault zone reveals its deep structures. |
