摘要
从理论上说,地球化学场与磁异常场的恒定关系是不存在的。但一个区域的地球化学特征与磁异常必然存在一定的关系,这种关系可能不是固定的。通过实际工作数据分析,证明了磁异常与地球化学异常确实有一定的关系,而且使用分频的磁异常研究与地球化学异常的关系会得到更合理的解释。分析的地球化学元素不同,与不同的频率磁异常会有不同的相关关系。
Theoretically,there is no certain relationship between geochemical maps and magnetic anomalies.However,there is some relationship between regional geochemical characters and magnetic anomalies.And it is not possibly fixed.Analyzing field data proved that there is certain relationship between magnetic and geochemical anomalies.Further,frequency division investigation of magnetic anomalies made the relationship explanation more reasonable.There are different correlations for different geochemical elements with the magnetic anomalies at different frequencies.
