摘    要:首钢秘鲁马尔科纳铁矿位于南半球低纬度地区,地磁场对磁性体的磁化以水平磁化为主,磁性体产生的ΔT异常与中国的△T异常特征差别很大,国内常用的化极方法在此类地区的应用文献少见,使用不当很难取得良好效果,虽然化赤方法在低纬度地区能取得较好的结果,但针对化赤异常的解释技术却相对较少.通过常规化极与化赤方法对秘鲁马尔科纳胡斯塔铜...

关 键 词:马尔科纳铁矿  低纬度地区  地磁异常  航磁异常  数据处理  秘鲁

Abstract:Shougang Hierro Peru Marcona Iron Deposit occurs at low latitudes in the southern hemisphere. The magnetization of the earth magnetic field to magnetic objects in this area is dominated by the horizontal magnetization. AT magnetic anomalies produced by magnetic objects here are greatly different from those in the mainland of China. At present, application of reducing to pole method commonly used in China is rare in literature and if it is not properly used here the result is poor. Comparatively speaking, the method of reducing to the equator can achieve better results in low latitudes but the interpreting technologies very few. In this article, both the two methods are used to process the geomagnetic data of Shougang Hierro Peru Marcona Justa copper mining area. The results are compared and recommendation of processing aeromagnetic data in this area is given.
Keywords:Marcona iron deposit  low latitude  ground magnetic anomaly  aeromagnetic anomaly  dsta processing  Peru
