There are three genetic types of mineral deposits in the Beiya ore district:① Cu-Au polymetallic deposits related to alkaline porphyries, comprising porphyritic Cu-Au deposits and polymetallic skarn deposits related to quartz-albite porphyry and quartz-K-feldspar porphyry;② Fe-Au deposits related to gabbro or basalt magma, consisting of magmatic Fe-Au deposits and sedimentary polymetallic deposits formed in caves and lakes; and ③ palaeo-placers formed at the weathering surface, in lakes and in karsts.
