摘要
快速准确有效的数据处理方法是日益增长的地学数据为成矿预测工作提出的迫切要求。提出了一种基于GIS的地球化学数据处理新方法,克服了传统统计分析方法对样本数据要求服从正态或对数正态分布,处理结果受少数特高品位数据影响的缺点。通过凤凰山铜矿地球化学数据处理的对比分析,认为该方法具有较好的抗干扰和致矿异常分辨能力。
Facing increasing data, more demands for fast accurate and effective data analysis method is made to ore prediction. A new analysis method based on geographic information system is put forward in this paper, overcoming the shortage of traditional statistics that analysis results are influenced by specimen distributes and the minority with higher content. According to the geochemical data analysis results of Fenghuangshan Cu deposit, the new method has a good anti interference and fine resolution to ore forming geo anomalies
