     Based on the 1 ∶200,000 geochemical data of stream sediments in Dongan -Tangwanghe region, Heilongjiang Province,correlation analysis,cluster analysis and principal factor analysis conducted on 13 ele-ments show systematic and regular element distributions.Anomalies of high-temperature elements and low-tem-perature elements occur in the western and eastern parts of the study area,respectively.Though computing the threshold by fractal analysis,it is proposed that the eastern area has substantial potential for exploring Au deposits associated with middle-to low-temperature elements.Combining the information of geology,geophysics and known deposits,this paper delineates 34 element anomaly associations and 4 potential prospecting areas.
