Abstract：This paper considers the lithosphere magnetic field of eastern-Dabie area (115~117.5°E,29.5~32.5°N). Through analysis and inversion, we get geomagnetic structure models of underground media, such as the shallow model of lithosphere geomagnetic field, deep model of lithosphere geomagnetic field and the depth distribution model of Curie interface. By analyzing features of distribution of some related magnetic anomalies, we discover that the positive anomaly magnetic field of lithosphere in eastern-Dabie area is in the structural unit of Jianghuai promontory, Tancheng-Lujiang fault zone and the depression of lower Yangtze platform; a huge EW trend geomagnetic negative anomaly passes through the northern Huaiyang fold belt. Comparing the magnetic field of lithosphere and the shallow model of lithosphere, we are able to discover some trends of hidden fault and depth of cut. The deep model of lithosphere magnetic field, to some extent, reflects the distribution and structure of the lithosphere basement in this area. Furthermore, the depth of Curie interface could reveal the distribution of magma activities in this area.
