运用地球物理方法研究深部地质结构是目前应用最广、最有效的方法。为了研究太湖穹窿的深部构造背景及太湖穹窿形成机制，作者利用重、磁资料反演计算获得太湖地区浅变质岩系顶界面、磁性层顶界面、居里面和莫霍面的深度，分析了各界面的特征，以及深部构造与太湖穹窿在成因上的联系。提出浅变质岩系底部为区内深部的主要滑脱面，在区域挤压力作用下，滑脱面上的塑性层增厚，使其上部岩层弯曲，形成穹窿 The use of geophysical methods to study deep geological structure is the most widely used and most effective method. In order to study the deep tectonic setting of Taihu Dome and the formation mechanism of Taihu Dome, the authors obtained the depths of the top, top, middle and mojo surfaces of the shallow metamorphic rocks in Taihu Lake using inversion of gravity and magnetic data. The characteristics of the interface, as well as the genetic relationship between the deep structure and the Taihu dome. It is proposed that the bottom of the shallow metamorphic rocks is the major slip surface in the deep part of the area. Under the action of compressive force in the area, the plastic layer on the slip surface is thickened and the upper rock layer is bent to form the dome
