英文摘要	The major elemental and oxygen isotopic features of Cretaceous granitoids in the coastal area of southeastern China cannot be adequately explained by existing Sr-Nd isotopic models of two-component crust-mantle mixing. In this paper, we report the whole-rock elemental, and Sr-, Nd-, and Hf-isotopes, and the zircon U-Pb age and HfO isotopic compositions for the Puqian, Danyang, Qingliangshan, Nanyu, and Qishan plutons in northeastern Fujian of this area to further investigate their petrogenesis. The examined rocks included pyroxene diorite, monzodiorite, granodioritic enclave, monzogranite and alkali-feldspar granite. Zircon U-Pb dating gave crystallization ages of 115 Ma for the Puqian monzogranite and granodioritic enclave, 97-109 Ma for the Danyang monzogranite, 99 Ma for the Nanyu pyroxene diorite, 97 Ma for the Qishan alkali-feldspar granite, and 97-103 Ma for the Qingliangshan alkali-feldspar granite. Our new Sr-Nd-Hf-O isotopic and petrogenetic studies of these granitoids showed that, aside from the ancient crustal component (delta O-18 = 7.5 parts per thousand, epsilon(Hf)(t) = - 10) and the mantle-derived magma (delta O-18 = 5.3 parts per thousand, epsilon(Hf)(t) = 2), a separate juvenile low delta O-18 crustal source (delta O-18 = 4,2 parts per thousand, epsilon(Hf)(t) = 2) must be involved. Since the emplacement of the diorite-monzodiorite-granodiorite-monzogranite suite and the A-type granite was coeval with pull-apart basins and bimodal volcanic rocks, the Cretaceous granitoids in northeastern Fujian, coastal area of southeastern China, were emplaced in an extensional setting, possibly due to the backarc extension and the changing drifting direction of the paleo-Pacific plate.
