By taking Gangdese copper-polymetallic metallogenic belt as an example, methods and thoughts to carry out geochemical subdivisions in metallogenic belt scale using 1∶200 000 and 1∶500 000 stream sediments data are expounded, and further the geological significances are discussed. The results show that geochemical data of the small-scale stream sediments have tracer significance for geochemical subdivisions. Therefore, a set of operable geochemical subdivisions methods is summed up, which is beneficial for prospecting direction and referenced for tectonic subdivisions.
