Basing upon the even function (the cosine series) in this paper is introduced a method including the total field reduced to the pole and its second derivative and the continuation for numerical processing of aeromagnetic data. The method presented here is much more accurate than that of the Fourier method, while the boundary effect is depressed to a certain degree. In addition, an example utilizing the method also shows it to be useful for the exploration of mineral deposits and study of geologic...

Basing upon the even function (the cosine series) in this paper is introduced a method including the total field reduced to the pole and its second derivative and the continuation for numerical processing of aeromagnetic data. The method presented here is much more accurate than that of the Fourier method, while the boundary effect is depressed to a certain degree. In addition, an example utilizing the method also shows it to be useful for the exploration of mineral deposits and study of geologic structures of the deep-seated crust. Finally, the computer program of the method is presented. By combining the Fast Fourier Transforms (FFT) with the recurrence process applied in the program, the computation time is shortened and the amount of data is less restricted.

本文通过实例对航磁资料进行垂直换算、垂直二阶导数和延拓计算的数字处理方法作了介绍。本方法以偶函数(cos级数)为基础,比一般富氏级数方法提高了计算精度,并改进了边界效应。文章最后给出的计算程序是采用了快速富氏变换算法和递推算法相结合,不但计算速度快,而且对计算点数也没有严格限制。这一计算方法对于找矿、地质构造与深部地壳分析都是十分有用的。

A series of data processing have been made from the regional gravity-magnetic anomalies in the focal area of the 1605 Qiongzhou great earthquake by regular methods.The gravity anomaly has been processed in 1 ) shallow deposition correction; 2 ) continuation upwards to 5 , 10, 15, 20, 25, 30, 40, 50 and 60 km; 3 ) moving average, with the area window being 20×20, 30×30, 40×40, 60×60, 80×80 and 100×100km2; and 4) Moho calculation.And the (△T ) aeromagnetic anomalt has been processed in 1 ) reduced to the pole; 2 ) continuation of ihe △T aeromagnetic anomaly after being reduced to the pole, with the continuation height being 5 , 10, 20, 30, 40 and 50 km; 3 ) first derivative calcnlation of the three vertical components in the △T aeromagnetic anomaly, △X, △y, △z; 4 ) gravity calculation from the magnetic sources; and 5 ) calculation on the depth of the Curie surface. This paper explains systematically the above calculating-processing results and the gravity-magnetic chracteri sties reflected by them, points out that the regional gravity-magnetic isoanomalic contour is distributed and changed regularly, that the major gradient zones, the isomorphic contorted zones and the joint zones of anomalies different in type and direction in all the anomaly isoline maps coincide and correspond to the whole. They can be tested and complemented each other. Moreover, the zones above are mostly distributed regularly in the NEE strike, secondarly in the NNW-NW and the NE diretions

作者对1605年琼州大地震震源区区域重、磁资料,依常规方法进行了一系列数据处理,包括布格重力异常的浅层沉积校正,向上延拓(9个上延高度)、滑动平均(6个方域窗口)、莫氏面反演,以及航磁△T的化极、化极向上延拓(6个上延高度),航磁△T的△X、△Y、△Z三个分量在垂向上的一阶导数、磁源重力、居里面反演等计算处理。本文系统阐述了各项计算处理的结果及其反映的重、磁场特征,指出所论区域重、磁异常等值线的展布及变化都很有规律,各项异常等值线中的主要梯级带及同形扭曲带,不同类型、不同方向的异常交接带,大体上比较吻合,可以互相对应,互为检验和补益;并且,其线性异常、异常等值线展布的梯级带或同形扭曲带,均以北东东走向有规律地分布为主,北北西—北西及北东走向者居次要地位。

In thise paper, a new method of reduced to the pole at low latitude by using descended the maximum step-by-step is presented. The tests on theoretical models and observed magnetic anomly show that the method can be well used to reduced to the pole for regional magnetic anomaly at low latitude ,and the accuracy is good. The paper resolves the problem of reduced to the pole at low latitude.
