云南金平老集寨铅锌多金属矿床位于滇西南哀牢山成矿带内,其探明储量已达中型规模.在前期勘查成果的基础上,分析该矿区的成矿地质条件、矿体特征及矿液运移规律,总结成矿规律和控矿模式等.结果表明:老集寨铅锌多金属矿床是典型的断裂构造及层间破碎带中充填交代的中低温热液型矿床.以已完成勘探阶段的依里矿段为中心,向北西和南东,在NW-SE向的金竹寨—老集寨大断裂北东盘约10 km2的区域为老集寨铅锌多金属外围找矿靶区,推断其为该区下一步铅锌多金属矿的找矿突破区域.
The metallogenic geological characteristics and exploration predictions of the Laojizhai lead-zinc polymetallic depoist in Jinping,Yunnan
The Laojizhai lead-zinc polymetallic deposit in Jinping County,Yunnan,located in the southwest-ern Ailao Mountain metallogenic belt,has medium-scale proven reserves.Based on the results of previous explorations,this study analyzes the polymetallic conditions,characteristics of ore bodies,and migration patterns of mineralizing fluids within the deposit,summarizing the metallogenic regularities and controlling factors.The findings indicate that the Laojizhai lead-zinc polymetallic deposit is a typical mesothermal hydro-thermal system,characterized by filling and metamorphism within fault structures and interlayered zones.Centered around the Yili mining section,which has completed the exploration stage,the northwest and southeast regions encompassing approximately 10 square kilometers within the northeast block of the NW-SE oriented Jinzhuzhai-Laojizhai large fault are targeted for further exploration of the Laojizhai lead-zinc poly-metallic periphery.It is inferred that this area holds potential as the next breakthrough region for lead-zinc polymetallic mining in the region.
