JADE算法在反演地球化学元素组合中的应用

根据盲源分离的原理及其化探数据的高度非线性性,提出了一种关于JADE算法处理化探数据的新方法,这种方法能有效地反演地球化学元素组合.与传统的方法相比,新方法能更好的适应化探数据的高度非线性性,能更好地圈定地球化学异常及异常浓度中心.利用这种方法对西藏某地区1∶20万土壤地球化学测量数据进行了处理,圈定出了传统方法不能圈定出的弱异常,所圈定的异常和矿化分布与实际情况基本一致.

The Application of the JADE Algorithm in Inversion of Geochemical Element Combination

Based on the principle of blind source separation and highly non-linear on geochemical data,a new method for processing geochemical data about the algorithm of JADE was proposed,which can effectively acquire an inversion of geochemical element association.Compared with the traditional methods,the new method can better adapt to the non-linear of geochemical data and extract the geochemical anomaly and its density concentration.It is found that the new method extract weak anomaly that the traditional methods can＇t extract and the mineralized distribution of the extraction anomaly are coincident with actual state through processing the soil geochemical survey data from an area of Tibet 1：20 million.
