AbstractThe Shi-Hang Zone is an important NE-SW-trending Mesozoic magmatic belt in South China, which is dominated by granites with relatively high epsilon(Nd)(t) values and young T-DM model ages. Here, we present laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) zircon U-Pb ages, major and trace element compositions, and Sr-Nd-Hf isotope data for the Yuanzhuding porphyritic granitoids within the southwestern Shi-Hang Zone, and use these data to determine the origin of this granitoid and its relationship with Cu-Mo mineralization. Zircon U-Pb dating indicates that these granitoids were emplaced at 157.8 +/- 1.1 Ma. They have initial Sr-87/Sr-86 ratios of 0.70941-0.71398, epsilon(Nd)(t) values of -3.15 to -2.02, and in situ zircon epsilon(Hf)(t) values of +1.71 to +6.17. Geochemically, most of them are high-K calc-alkaline and show an adakitic affinity. They are more likely emplaced in a continental arc setting related to westward subduction of the paleo-Pacffic plate. Their parental magma originated chiefly from the overlying sediments of the downgoing slab, and subsequently interacted with the lithospheric mantle wedge at the temperatures of similar to 790 degrees C. High oxygen fugacity during magmatic evolution played a crucial role in the development of Cu-Mo mineralization within the Yuanzhuding. The discovery of the Yuanzhuding deposit implies that the Chenzhou-Huaiji fault belt is most likely prospective for mineral exploration for porphyry Cu-Mo deposits. (C) 2013 Elsevier B.V.
