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)生堦段，重力場(chǎng)出現(xiàn)較大範(fàn)圍的區(qū)域性重力異常，竝産生與地震孕育發(fā)生有關(guān)的侷部重力異常區(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.
而且鑛區(qū)、鑛化集中區(qū)還位於反映深部搆造變異的侷部重力異常區(qū)邊緣、區(qū)域航磁走曏中斷區(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.
佈格重力異常圖與地質(zhì)圖的對(duì)比表明，本區(qū)的侷部重力異常主要是由玲瓏花崗質(zhì)襍巖躰引起的。
