磁法勘探在屏山磁铁矿勘查中的应用

摘要

We applied the ENVI MAG proton magnetic gradiometer and FVM -400 magnetic saturation magnetometer to conduct magnetic survey on the ground and in the adit in Pingshan to get the the ground measured AT anomalies and the profile of adit AT anomalies.Contrast processing and interpretation with the data of AZ and Geological data provided by the mining area, On the basis of Analysis Magnetic anomaly made by Geologic reason in the mining area. Delineated the anomaly range and distribution characteristics, inferred the Magnetite ore's downward continuation condition.%利用地面ENVI MAG质子磁力梯度仪和FVM-400磁饱和式磁力仪,对屏山铁矿地面上和平硐中进行了磁测,获得该矿区地面实测△T异常及平硐中的△T异常剖面.通过与矿区提供的原有实测数据及地质资料,对比处理与解释,在分析该矿区磁异常产生的可能地质原因基础上,圈定了异常体的范围和分布特征,推断了磁铁矿体的下延情况.
