| 摘 要： | 在西南三江北段的地质、地球化学、地球物理等综合信息找矿模型研究基础上,运用聚类分析和因子分析方法,对选取的五十一个因子进行全面的研究,为该区的进一步工作提供重要的找矿信息。经研究结果表明:传统的多元统计分析在地质数据处理中的作用应该值得肯定,它对于归纳和优选地质信息组合以及通过地质信息组合特征分析、解释成矿过程和成矿元素的迁移、富集变化,判定成矿阶段具有重要的参考与指导作用。

| Abstract: | Based on the prospecting model of integrated information of geology, geochemistry and geophysics for the north section of the Jinshajiang-Lanchangjiang-Nujiang region, a total of 51 prospecting factors have been selected and comprehensively analyzed by using cluster analysis and factor analysis, and with some important prospecting information for further exploration provided. The results show that the conventional multivariable statistical analysis is still very useful for comprehensive selecting of combined geological formation, understanding of ore-forming process, and element migration and enrichment. |
