| 摘 要： | 河南省丰富的铝土矿资源，均属层状、似层状和溶斗状矿床，其物理性质与围岩无明显差异。因此，一般物探方法找矿效果不佳。但高精度重力测量却可以探测到具有一定横向密度变化的溶斗状铝土矿体所引起的异常。本文列举了应用微重力测量寻找深部隐伏铝土矿体的成功实例。

| Abstract: | The resources of bauxite occurred as the stratiform,stratoid and solution funnel in Henan Province are the abundant.The difference of physical property between bauxite and its wallrock is not obvious.Therefore,the prospecting results by the general geophysical prospecting method are not very good.But high precision gravimetry can probe the anomaly caused by the solution funnel bauxite bodies having fixed lateral density changes.The successful living example in the application of the minigravity survey to find the deep hidden bauxite ore has been enumerated in this paper. |
