With the further prospecting and exploration degree enhancement, the surface deposits have become less and less, prospecting work towards the deep, hidden deposits, the traditional method can not satisfy the actual demand, resulting in ore prospecting and prediction of mineral resources work is facing new challenges. Geochemical element carrying a large number of geological information, analysis of these elements is an important work of prospecting. Because the distribution of geochemical elements has heterogeneity, randomness, uncertainty characteristics, causing the complexity analysis of geochemical elements. Distribution characteristics of ore prospecting work in-depth development and elemental geochemistry, force analysis and geochemical anomaly of the earth is facing new challenges, to research the new technology and new method to deal with the increasingly difficult prospecting work.Independent component analysis as a new signal processing method, because of its theory of higher-order statistics based on the advantages, the rapid development in recent years, a wide range of applications. Independent component analysis based on the assumption that the statistically independent source signals based on the analysis of data, information of the higher order statistics, linear transformation, to achieve the maximization of data than Gauss. Application of ICA theory for feature extraction, can highlight the original data implied information, this paper is based on the idea of the.By studying the theory of ICA, analyzed the data of the spheroidizing process, the establishment of the target function and optimization criteria to achieve. Focus on the theory of JADE algorithm model, established the flow of JADE algorithm. On the basis of JADE algorithm and geochemical element anomaly extraction model based on. Geochemical data feature extraction using JADE algorithm, and highlights the geochemical anomaly information in the data, and using the correlation theory to solve the feature extraction sequence corresponding relation, find out the corresponding element of data processing. In the JADE feature extraction, calculation of abnormal lower delineation of data anomalies, abnormal output maps, combined with the geological background of actual area analysis results, verify each other.The research and analysis of the theoretical model based on the software platform, the construction of the geochemical data processing. Taking VC6.0as the development tool, combined with the idea of object-oriented software. The software through the bottom of the hanging database to realize data transmission, with MFC single document to achieve interactive operation desk. Integrated software commonly used in data analysis method and threshold method, in order to form a set of easy operation, high practicality and geochemical data processing software platform.
