The Huogeqi copper-lead-zinc polymetallic deposit in Inner Mongolia is located in the western part of the Middle-Late Proterozoic Langshan rift trough situated on the northern border of North China Platform. Previous studies suggest that the Huogeqi deposit is a sedimentary exhalative deposit and that the main metallogenic epoch was the Middle-Late Proterozoic, with metallogenic superimposition or transformation in later period. There is a lack of necessary chronological evidence of ore sulfides, required to support mineralization events later. This work conducted Rb-Sr dating of sulfides to constrain the metallogenic epoch of this deposit, which provides good chronological evidence for the comprehensive study of copper-lead-zinc-iron mineralization in this area.
