Abstract: Fluid geochemistry is a frontier of research in international earth science field,and tracing on information of fluid movement is another focus of research at present. In past time,isotopic method and REE geochemical method were used to study source of mineralizing material and mechanism of ore-forming,but were not so fully and widely used in tracing tracks of ore-forming fluid. So,in this essay,the emphasis of research is on the tracing of ore-forming fluid movement.
