磁异常化极是磁测资料处理和解释的重要基础,在大面积磁法测量及编图工作中,测区内磁纬度的变化范围很大,多个图幅资料只采用单一的磁倾角作化极处理显然是不合理的,必须考虑变磁倾角的处理方法.本文针对这一问题,改进常规的化极实现途径,尝试了在频率域进行大区域逐点变磁倾角实现化极的方案.理论模型和实际资料均表明,该方法在磁倾角变化范围很大的情况下,数值恢复精度比传统方法有较大提高,对目前大面积矿产资源磁法勘探资料连片处理具有实际意义.
Magnetic anomaly is an important basis for magnetic data processing and interpretation. In large-area magnetic measurement and charting work, the magnetic latitude in a survey area varies greatly. A single magnetic dip angle is used for multiple map data It is obviously unreasonable to deal with magnetization pole, and we must consider the treatment method of magnetization dip.Aiming at this problem, this paper improves the conventional ways to realize magnetized pole, Both the theoretical model and the actual data show that the numerical recovery accuracy of this method is greatly improved compared with the traditional method under the condition of large variation of the inclination angle, which is of practical significance for the contiguous processing of the magnetic prospecting data of the large area mineral resources.
