| 摘 要： | 本文利用39个地温梯度值及估算的热流值讨论了本区地温场的分布特征。并求取了居里等温面。结果表明:(1)全区平均地温梯度为3.2℃/100m,平均热流值为1.5HFU;(2)居里面的深度为14—34公里,强震主要发生在居里等温线的梯度带上。最后就地温场与地震的关系做了初步分析。

| Abstract: | This paper deals with the features of geothermal field in the investigated area. By means of the data of 38 geothermal gradient and their calculated heat flow values, Curie isothermal surface has been calculated. The results are:1. The mean geothermal gradient in this investigated area is 3.2c/100m; and the mean heat flow value is 1.52 HFU.2. The depth of Curie isothermal surface in the different regions changes from 14 km to 34 km below sea level. In the belt of Curie isothermal gradient occurred strong earthquakes principally. Finally the preliminary study was done on the relationship between geothermal field and the occurrence of earthquakes. |
