Ore deposits of this region are assigned to Caledonian metallogenic series and Indosinian metallogenic series according to ore-bearing strata, granites related to ore deposits mineralization type and temporal-spatial distribution characteristics of ore deposits. The Caledonian series is further divided into three subseries, namely lead and zinc metallogenic subseries, lead, zinc and iron metallogenic subseries and lead, zinc, tungsten, tin and molybdenum metallogenic subseries.
