Abstract The geochemical data of stream sediments contain significant geological and geochemical information. In this study, R factor analysis method was applied to 1∶250 000 stream sediments data from Western Qilian Mountain. Five geochemical zones were recognized and their geological implications were discussed according to element association. The geochemical zones correspond to the tectonic units, and therefore these results can provide abundant geochemical implications for basic geology research, prediction of prospective areas and further division of Grade IV ore-forming belts.
