Porphyry copper deposits are the most important copperdeposits in the world and in China too.The metallogenic epoch of the deposits is mainly Yanshanian. The known porphyry copper deposits can be grouped into 3 mainmetallogenic belts and further into 6 model areas. 12 predicting variables are selected to predict porphyry copper deposits. Using the multiinformation integration and assessment system, the authors have assessed 10 prospect areas for porphyry copper deposits.
