Geological and geochemical background analysis shows that the Baoshan metallogenic belt has favorable metallogenic conditions and prospecting potential.Based on probing into the geological-geochemical characteristics and ore-forming regularity of the main large-size and medium-size Pb-Zn deposits,the authors put forward a " four zones,four storeys and three types" characteristics of PbZn mineralization in the Baoshan metallogenic belt,which provides theoretical basis for geological-geochemical prognosis of regional PbZn deposits.Based on analyzing the characteristics of four main Pb-Zn anomaly zones,this paper establishes prospecting models of the comprehensive information.The favorable zones for exploration and major types of ore deposits are pointed out,which is helpful to further ore-prospecting work.
