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.
