Abstract:Based on the previous geology and other research results, according to regional gravity and magnetic data, this paper analyzed the gravity and magnetic features and also processed and explained the low gravity anomaly in Zhaotong Basin. The basement structure form, strata development characteristics and fault structure distribution were revealed in detail through basement density interface inversion and profile inversion based on gravity data. And the effect of the fault and fold structure in the processing of huge thick lignite layer was analyzed in Zhaotong Basin. So it is concluded that Zhaotong Basin is a tectonic depression basin.
