Abstract Copper deposits in Guangdong Province are characterized by dispersion of occurrences, varied types and concentrated reserves. With eight typical copper deposits as examples, the authors investigated copper anomalies and element combination characteristics, and have reached the following conclusions:Copper enrichment position can better reflect the known ore deposit; Different types of copper deposits with similar sizes have similar copper anomaly areas, but their copper average values are different considerably; Cu, Mo, Sb combination of porphyry copper deposits, Cu, Pb, Zn, Ag, Cd, Bi, Mo, W, Sn, Mn combination of multiple genetic deposits and Cu, Pb, Zn, Cd, Ag, As combination of volcanic rock type copper deposits are fairly stable. These results provide some scientific basis for understanding of copper metallogenic regularity and carrying out geological survey and geological evaluation in Guangdong Province.
