local gravity anomaly

基本解释

In the genesis stage of an earthquake, regional gravity anomaly appears in a large area, resulting in related local gravity anomaly.
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。
Ore zones occur in the edge of local positive gravity anomaly, in the strike interrupted area or steep gradient area of regional aeromagnetic anomaly.
而且矿区、矿化集中区还位于反映深部构造变异的局部重力异常区边缘、区域航磁走向中断区或梯度变化带附近。
Comparison of the Bouguer gravity anomaly map with geological map shows that the local negative gravity anomaly 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。
