因子分析在地球化学分区中的应用——以广东周田地区1:5万水系沉积物测量数据为例

摘要

Using R-mode factor analysis to process the data obtained from the measurement of stream sediment in studying area, it has concluded 5 representative factors, by fully extracting the geochemical background information contained in the sample and conducting geochemical subdivision studies, the geochemical subdivision map that can reflect the overall geologic characteristics of the study area has been drawn. The results show that the obtained geochemical subdivision map corresponds well with the geological features and the ore spots.%采用R型因子分析方法,对广东周田地区1︰5万水系沉积物测量数据进行了处理,优选了具有代表性的5个因子,通过充分提取样品中所蕴含的地球化学背景信息,进行地球化学分区研究, 绘制了能够反映研究区整体地质特征的地球化学分区图.结果表明,所得到的地球化学分区与地质特征及矿点对应较好.
