Abstract: The secondary development of geological materials is based upon re-understanding of geological phenomena,re-explaining geological questions,re-processing geological data,re-extracting geological information for maximizing application of original geological data in the production and scientific research under guided by the new metallogenic theory.On the basis of previous researches,author summarize method for secondary development of geological materials and discusses following three respects:re- processing geological data,re-evaluating geophysical and geochemical anomalies,re- concluding metallogenic regularities,in order to fully utilize multitudinous geological data in geologic prospecting to metallogenic forecast.
