local gravity anomaly

基本解釋

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(fā)生階段，重力場(chǎng)出現(xiàn)較大范圍的區(qū)域性重力異常，并產(chǎn)生與地震孕育發(fā)生有關(guān)的局部重力異常區(qū)。
Ore zones occur in the edge of local positive gravity anomaly, in the strike interrupted area or steep gradient area of regional aeromagnetic anomaly.
而且礦區(qū)、礦化集中區(qū)還位于反映深部構(gòu)造變異的局部重力異常區(qū)邊緣、區(qū)域航磁走向中斷區(qū)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.
布格重力異常圖與地質(zhì)圖的對(duì)比表明，本區(qū)的局部重力異常主要是由玲瓏花崗質(zhì)雜巖體引起的。
