摘要 

本文叙述适用于特殊磁场区航磁解释的新方法,包括弱信号增强,自调节滤波和解析信号.其目的是获得在原始数据上反映不明显的有关找矿标志和地质构造的信息.这些方法已用于分析湘南弱磁区和内蒙火山岩区的航磁数据,结果证明这些方法对改进地质填图具有很好的效果.

Abstract

This paper describes new methods suitable for aeromagnetic interpretationof special magnetic fields, which include intensification of weak signal, self-adjusting filter and analytic signal. The purpose for adopting these methodsis to obtain information related to ore-prospecting indicators and geologicalstructures which is not shown distinctly in the initial data.The application ofthese methods to the analysis of aeromagnetic data from the weak magneticarea of southern Hunan and the volcanics area of Inner Mingolia has provedthat these methods are effective in improving geological mapping.
