| 摘 要： | 本文给出了京津唐地区居里等温面的计算结果。本区居里面的深度约为16-26公里。然后讨论了居里等温面与地震的关系,得出各地区之间地壳温度场的差异产生的应力可能是地震发生的一个重要原因。

| Abstract: | The paper studies the spatial variation of the Curie point isotherms in Beijing-Tianjin-Tanshan area with the help of aeromagnetic data. The depth of this isothermal surface in different regions changes from 16 km to 26 km below sea level. It is shallower than those in the tectonic regions in other parts of China. It was found that the stress due to the difference of the temperature between two adjacent regions is very important for earthquake occurrence. |
