| Abstract: | The study area is a complicated scenery geochemical area. The sampling site is frequently migra- tory. The high value point of sample is determined difficultly. The area of weak geochemical anomaly outlined with the routine method is large. And the anomaly centre isn＇t clear. We have standardized the geochemical data, out- lined the geochemical anomaly by cluster analysis, factor analysis and comprehensive contrast calculation, which can be used in the field prospecting. And many Cu ore bodies （occurrence spot） have been found out. |
