The Aonaodaba porphyry copper-silver-tin polymotallic deposit is different both from most porphyry copper deposits formed by derivatives of mantle magma and from most porphyry tin (tungsten, molybdenum) deposits produced by derivatives of crustal remelted magma. It is a porphyry copper-silver-tin deposit that occurs in the transitional crust and was formed by derivatives of the lower crustal-upper mantle transitional magma. According to data available, the distribution of magnetic, electrical and geochemical anomalies in the ore district is consistent with the known minsralization-alteration zone. Where there are integrated anomalies formed by consistent magnetic, electrical and geochemical anomalies, there are orebodies revealed by drilling inspection.
