基于RAGA的PPC模型在化探异常分析中的应用——以凤太矿集区为例
Application of RAGA-Based PPC model to analysis of geochemical anomaly——A case of Fengtai mineral cluster region
摘要
Abstract
To distinguish the geochemical background and geochemical anomaly is the key of geochemical data processing and information extraction has a direct impact on the results of ore prediction. This paper introduces the application of RAGA-based PPC model to procession of 1∶50000 stream sediment data from Fengtai mineral cluster region and probes into use of projection pursuit cluster in recognition of geochemical anomaly and the symbolical elements combination, as well as the geological significance represented by the value of the projection direction. Results show that, PPC model for geochemical anomaly recognition is better than the traditional method and provides a new thinking and approaches for multi-dimensional processing of geochemical data.关键词
