Abstract:The Southeast of Chongqing is located in the Pb-Zn mineralization zone in the south margin of the central part of Yangzi paraplatform,also is the major area of Pb-Zn ore production in Chongqing.The paper summarizes the geological characteristics of typical Pb-Zn deposits in Southeast Chongqing,which occur mainly as the reworked sedimentary-hot brine type,and are similar to Mississippi Valley type lead-zinc deposit.The paper also analyzes the advantageous geological conditions for mineral forming from metallogenic controlling lithology,lithofacies,structures,and the source of ore-forming fluids and deposition mechanisms of ore-forming materials,and gains the knowledge of the regularity of Pb-Zn mineralization in this area,summarizes prospecting indicators in this area.
