摘要: The composition of continental crust has always been an interesting subject for many geologists. However, the big difficulty is how to determine the composition of the deep crust, especially the composition of the lower crust. The identification of adakite-like rocks within the continental crust may provide a possible way to make sense of the problem. The geochemical characteristics of C-type adakite-like rocks in the eastern China show that they are the products of partial melting of intermediate to mafic granulites in the deep lower crust in high P-T condition, the composition of the lower crust therefore can be traced by these adakite-like rocks. Our preliminary studies show that the geochemical characteristics of adakite-like rocks are different from place to place in the eastern China, suggesting that the lower crust sources from which the adakite-like rocks are derived varying in the compositions from place to place too. Based on the Sr-Nd isotopic compositions of these adakite-like rocks, the lower cru
