二维EMD方法在物化探数据处理中的应用研究——以云南个旧地区为例

摘要

文章采用二维EMD方法对云南个旧地区物化探数据进行非线性的多尺度分析与分解,有效分离了物化探异常,揭示深层次找矿信息.证明了二维EMD分解得到的所有分量都具有实际地质意义,它将是一种新的物化探数据处理方法.%This paper applies bidimensional empirical mode decomposition(EMD) technique to multi-scale non-linear analysis and decomposition of geophysical and geochemical data of Gejiu area and geophysical and geochemical anomalies are separated and delineated so as to provide deep level ore information. Each component of EMD decomposition has its practical geological significance. EMD will be a new technique for geophysical and geochemical data procession.
