%X Adakite is associated closely with the epithermal and porphyry Au, Cu and Ag deposits, and most of large porphyry copper deposits in the Circum-Pacific Belt are related to adakite. The key factor to form the deposits in the adakite is the dehydration from amphibole to garnet during the formation of adakite, which exacts the metal elements enriched in the mantle and mafic rocks into the adakite. The localities of adakite are therefore usually related to the Cu and Au mineralization. China is a country short in copper resource. To find large and superlarge porphyry copper deposits are probably a sustainable way to solve the shortage. The majority of the world-scale copper deposits occur in the Circum-Pacific Belt, whereas similar deposits in China occur not in the eastern China, but in the Paleo-Asian Oceanic Belt, the eastern part of NE China and Gandise Mountain of Tibet. It is suggested here that the further exploration be aimed at the epithermal and porphyry Au, Cu and Ag deposits in the Paleozoic Paleo-Asian Oceanic orogenic belt, Late Paleozoic-Mesozoic the eastern part of NE China and Mesozoic-Cenozoic Gandise Mt. of Tibet, in particular in the southwestern margin of Altun-eastern Zungar, eastern Tianshan and middle Inner Mongolia areas of the Paleo-Asian Oecanic orogenic belt. Since adakite is like an indicator of these kinds of ore deposits, the exploration strategy should be processed to find adakite first, then the deposits.
