因子分析在水系沉积物测量地球化学分区中的应用探讨——以青海都兰地区为例

Discussion of applying factor analysis to the geochemical subareas measurement in stream sediment-A case study of Dulan area in Qinghai Province

采用R型因子分析方法,对工作区水系沉积物测量所取得的数据进行了处理,提取具有代表性的6个因子,并制作了因子计量图,用以描述工作区中主要的元素组合类型,为地球化学综合异常类型的划分与圈定,提供了较好的依据。

Using R-mode factor analysis to process the data obtained from the measurement of stream sediment in studying area, it has concluded 6 representative factors, and executed factor score map, which will be used to describe the combination types of major elements in studying area. It has also provided a better reference for the plotting and delimitation of the geochemical comprehensive anomalies types.
