By summarizing and studying the data of geochemical divisions in the west Tianshan of Xinjiang,China,the enrichment coefficients of 12 common ore-forming elements are calculated; the correction coefficients formula is put forward,and variation coefficients are reasonably corrected and sorted. Combining with the case deposit and mineralized points,the validity and applicability of correction coefficients is confirmed and the restrictive relationship between enrichment coefficients and variation coefficients in ore-forming process is summarized. By this way,it is possible to compare the ore conditions among different ore-forming elements and the applicability of geochemical parameters is broadened. Besides,the study improves the accuracy of geochemical evaluation methods in low exploration degree areas and provides scientific basis for geochemical evaluation.
