The residualgravityanomaly 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。

However, there occurs 5-70 milligals gravityanomaly in this region, the residual anomaly being 30-50 milligals after eliminating the effect of Mohorovicic discontinuity.
