首次从秦岭-大别山地区重力场中分解出由于莫氏面深度变化引起的区域重力异常和反映秦岭-大别山造山带地壳构造的剩余重力异常。秦岭-大别山地区的莫氏面由东部的32km,经过两个台阶,逐步加深到西部55km。剩余重力异常展示出秦岭-大别山地区有两条中生代俯冲岩浆岩带。北部岩浆岩带包括西秦岭与东秦岭岩浆岩带,经过南阳盆地后,向合肥盆地北缘方向延伸,尖灭于阜阳以西,南部岩浆岩带与桐柏-大别山地区重合。东秦岭的西部重力低,应为早古生代凹陷的反映。
For the first time, the regional gravity anomalies caused by the variation of Mohsian surface depth are resolved from the gravitational field in the Qinling-Dabie Mountain area and the residual gravity anomalies reflecting the crustal structure of the Qinling-Dabie orogenic belt. The Mohsian surface in the Qinling-Dabie Mountains ranges from 32km in the east to two steps and gradually deepens to 55km in the west. The remaining gravity anomaly shows that there are two Mesozoic subducted magmatic belts in Qinling-Dabie Mountain area. The northern magmatic belt includes the West Qinling and East Qinling magmatic belt, after the Nanyang basin, extending to the north edge of the Hefei Basin, pinch out west of Fuyang, the southern magmatic belt and Tongbai - Dabie Mountain area coincide. The low gravity of the western part of the East Qinling Mountains should be a reflection of the Paleozoic depression.
