Abstract: The rapid economic development in recent years has led to the increased demand for leadzinc mineral resources, putting huge pressure on Chinas leadzinc reserves. Therefore, a nationwide comprehensive assessment on the status of leadzinc geological survey and mineral prospecting is much needed to aid future resource management in areas of resource prediction, identification, deployment and rational utilization. Here, we performed comprehensive analyses on the metallogenic, geological and spatiotemporal distribution characteristics of leadzinc deposits in 29 provinces, using the classification scheme developed in the national key mineral resources potential assessment project. We divided the prediction types of leadzinc deposits into nine types according to traditional ore deposit model, namely the stratabound carbonate (MVT), carbonate to fine clastic rock (SEDEX), glutenite, sedimentaryreworked, continental volcanic, marine volcanic, magmatic hydrothermal, skarn and weathering crust types. We also analyzed the prediction types and metallogenic epoch of leadzinc deposits in key metallogenic belts, documented the regional prediction factors of main leadzinc deposits in each metallogenic belt, and established the main regional prediction models for leadzinc deposits. Incorporating tectofacies, metallogenic belts and forecasting area distribution maps of China, we identified 15 metallogenic provinces and 47 levelⅢ leadzinc metallogenic zones, where mineral resource potential evaluation and prediction were performed. Our work provided a framework for future leadzinc prospecting.
Key words: leadzinc deposits, metallogenic zone, mineral prediction type, prediction model, mineral resource potential assessment
