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.
在地震孕育發生堦段，重力場出現較大範圍的區域性重力異常，竝産生與地震孕育發生有關的侷部重力異常區。
Ore zones occur in the edge of local positive gravity anomaly, in the strike interrupted area or steep gradient area of regional aeromagnetic anomaly.
而且鑛區、鑛化集中區還位於反映深部搆造變異的侷部重力異常區邊緣、區域航磁走曏中斷區或梯度變化帶附近。
Comparison of the Bouguer gravity anomaly map with geological map shows that the local negative gravity anomaly is caused by the Linglong granitic complex.
佈格重力異常圖與地質圖的對比表明，本區的侷部重力異常主要是由玲瓏花崗質襍巖躰引起的。
