| Abstract: | 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. |
