摘要
华南中部的重、磁场,从表面上看似乎复杂,经研究表明,它的区域场则是比较单一。江南、华夏两古陆所引起的是一复合的等轴磁异常,它与“半鸟”形式的重力布格异常相对应。这个磁异常的周边非常明显。报据重、磁场的特征,完全可以建立该区的地壳模型以及勾划其区域地质构造轮廓。
The gravity and magnetic fields in the middle of south-China appears complex, but the study shows its regional field is simpler. What the two ancient lands of Jiangnan and Huaxia caused is a complex magnetic anomaly of equal-axises which corresponds to the gravity Bouguer anomaly in form of 'peninsula' . The periphery of the magnetic anomaly is very obvious. According to the features of gravity and magnetic fields, it is possible to build the crust patterns in this area and draw the structure outline of its regional geology.
