In the genesis stage of an earthquake, regional gravityanomaly appears in a large area, resulting in related localgravityanomaly.
在地震孕育发生阶段,重力场出现较大范围的区域性重力异常,并产生与地震孕育发生有关的局部重力异常区。

Comparison of the Bouguer gravityanomaly map with geological map shows that the local negative gravityanomaly is caused by the Linglong granitic complex.
布格重力异常图与地质图的对比表明,本区的局部重力异常主要是由玲珑花岗质杂岩体引起的。

As the second derivative does, the forth, derivative of gravityanomaly projects local anomaly but suppresses regional anomaly.
