1983年,我们应用航磁ΔT资料和“异常能谱”方法求解了辽宁地区深部磁性块体统计平均埋深。其成果图件使我们初步看到了本区深部磁性界面的起伏状态和磁性不均一的特征;通过深部磁界面与辽河裂谷型地温场分布的对比,可以看到深部磁界面与地热、地温场间的密切关系;地壳深部探测剖面提供了断裂与深层磁界面关系的线索;特别是NW向深层磁界面梯级带的存在,可为7.3级海城地震的发震构造提供深部背景和热应力依据。
In 1983, we applied aeromagnetic ΔT data and “anomalous energy spectrum” method to solve the statistical average depth of deep magnetic blocks in Liaoning. The results show that we have initially seen the region of the deep magnetic interface undulating state and the characteristics of the magnetic heterogeneity; through the deep magnetic interface and Liaohe rift-type geothermal field distribution comparison, we can see the deep magnetic interface and geothermal, geothermal field The deep crustal profiling of the crust provides clues to the relationship between the fault and the deep magnetic interface. Especially the presence of the NW-deep stratospheric cascade can provide deep background and thermal stress for the seismogenic structure of the Haicheng earthquake of magnitude 7.3 .
