本文利用天然地震转换波法所测得的漂阳震区地壳深部主要界面的构造图。简要地讨论了溧阳震区深部构造与震中分布的关系,认为溧阳两次中强地震都发生在较厚的花岗岩质层中,其深部构造特征表现为上地幔隆起、或界面埋深变化剧烈的梯度带,同时又处于两组以上深断裂交汇的特殊部位。 In this paper, we use the natural seismic wave transform method to measure the deep crust in the drift-yang region, the main interface of the tectonic map. The relationship between the deep structure and the epicenter distribution in the Liyang earthquake area is briefly discussed. It is considered that both of the moderately strong earthquakes in Liyang occurred in the thicker granitic bedrock, and the deep structural features of the Liyang earthquake region are the uplift of the upper mantle or the drastic change of the buried depth of the interface Gradient belt, at the same time in the two groups of deep fracture at the intersection of special parts.
