Abstract: Geological mineralization used to be the basis of the metallogenic series concept.To connect with the geological background studies and facilitate mineral forecast and prospecting, the research on the metallogenic series was conducted according to the relative period of geological formation and mineralization.Various metallogenic series related to geological formation were divided into syngenetic, penecontemporaneous and epigenetic series. With reference of pre-existing deposit metallogenic series, on the basis of three metallogenic belts, the main minerogenetic series of mineral deposit in Ordos were studied, and 18 series related with 11 kinds of geological formation were identified.
