Abstract:On the basis of studying regional geological background and mineralization characteristics of Dawenkou basin, analyzing minerals sources, the origin, minerals enrichment and evaporation deposition, metallogenic model of Dawenkou basin has been established. It is regarded that mineralization in Dawenkou basin is specific objective product controlled by regional background. Metallogenic oreforming materials is region basin edge formation. The metallogenic substance collected in this basin by water migration and the saline minerals is formed after evaporation deposition.
