Based on the least square method，linear correlation and statistical tests between Au and Sb determined by geoelectric chemistry method in 126 samples of line 41 to 46 at gold-antimony orefield in Longshan，Hunan Province.The same analysis was also conducted between integrating anomaly characteristics of Au and As-Ab-Hg that separated by sequential extraction.The obtained correlation coefficients were 0.895（Au and Sb） and 0.859 （Au and As-Ab-Hg），respectively，bigger than the critical value（0.811），suggesting the significant correlation between gold and associated elements.The test results were in good agreement with known combination features of the abnormal geochemical element in the mining，which can be applied for analysis of quality evaluation. Therefore，it is considered that the analysis results are reliable.Under the conditions without appropriate standard substances or duplicate sample monitoring，geochemical analysis element correlation evaluation method was proposed，which is advantageous to the geochemical prospecting popularization and application.
