【Abstract】 Based on the features of gravity and magnetic anomalies and the obvious difference of densities between eclogite observed at Maobei, one of the main targets of the continental deep scientific drilling, and the surrounding rocks, two inversions of the gravity anomalies are carried out, one of which is for the equivalent distribution of densities under no constraints, and another under the constraints of seismic data. The gravity models are given and can be taken as a base of further geological and geophysical research of this area.更多还原
