residual gravity anomaly [地物] 剩余重力异常
However, there occurs 5-70 milligals gravity anomaly in this region, the residual anomaly being 30-50 milligals after eliminating the effect of Mohorovicic discontinuity.
然而，在此区却出现了5—70毫伽的重力异常值，从中去除莫氏界面的影响，其剩余异常值还有30—50毫伽。
The residual gravity anomaly was mainly produced by rolling basement of the basin and the regional gravity anomaly by the Moho rolling.
推断引起剩余重力异常的主要原因是盆地基底的起伏，引起区域重力异常的主要原因是莫霍面起伏。
