摘要
对江苏东海县毛北地区重、磁观测异常进行了处理和特征分析 ,并根据科学钻探主要目标体榴辉岩与其围岩有达 0 .9× 1 0 3kg/m3的明显密度差 ,进行了等效密度反演成像与综合地震约束反演计算 .给出了该地区重力异常模型 。
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.
