The undulation of Mohorovicic discontinuity under JX region only causes the gravity anomaly of 21-42 milligals.
在JX地区，由莫氏界面的起伏只能引起21—42毫伽的重力异常值。

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.
