Abstract:

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. 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. In short, the geochemical subdivisions can guide for prospecting direction, mineral evaluation and basic geological survey.

Key words: small-scale stream sediment, Gangdese, copper-polymetallic metallogenic belt, geochemical subdivision
