摘　　要：额济纳旗沙尔德勒铅锌矿是近年来在内蒙古北山成矿带哈珠-雅干深大断裂带上新发现的一处铅锌矿床,矿体赋存于雀儿山群上组大理岩建造中,北东东向断裂旁侧的次级北西西向构造蚀变带是区内主要的控矿构造,围岩蚀变具硅化、黄铁矿化、碳酸盐化、绿帘石化及高岭土化等,属于中—低温热液矿床。含矿构造蚀变带地球物理特征呈现低阻高极化特征,地球化学异常元素组合以Pb、Zn、Ag、As等为主、各元素浓集中心明显、异常强度高。根据工作区地球物理、地球化学、含矿建造、矿体特征、围岩蚀变等特征,初步认为沙尔德勒铅锌矿深部具有较好的找矿潜力。The Shahedele lead-zinc deposit in Ejina Banner represents a recent discovery of a lead-zinc deposit in the Hazhu Yagan deep fault zone.The ore body is situated within the upper formation of the Queershan Group marble formation,with the nearly east-west secondary fault acting as the controlling structure in the area.The surrounding rock alteration is characterized by silicification,carbonation,epidotization,and kaolinization,and is indicative of a mesothermal deposit.The geophysical characteristics of the ore-bearing structural alteration zone exhibit high resistance and high polarization.The geochemical anomaly elements are primarily composed of Pb,Zn,W,Mo,and so forth,exhibiting discernible concentration centers for each element and a notable anomaly intensity.Based on the geophysical,geochemical,ore-bearing construction,ore body characteristics,and rock alteration data collected in the work area,it can be preliminarily inferred that the Shaldere lead-zinc mining area has good prospecting potential.
