摘要
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.ΔT 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.
