Porphyry copper deposits make up one of important types of copper deposits in the world. According to incomplete statistics, Cu resources from porphyry copper deposits account for 44.04% of the total Cu resources of China. Therefore, strengthening the prospecting and exploration of porphyry copper deposits is of great significance in solving the problem of Cu shortage in China. This paper comments on the situation of porphyry copper deposits in the world, dealing with such problems as source regions and host rock features of porphyry copper deposits, geological significance of the mash zone, relation of adakite to porphyry copper deposits, geological significance of transitional magma, and the general genetic model for porphyry copper deposits. A summarization is also given to porphyry copper deposits in China.
