| 英文摘要 | Raohe Complex, located in the eastern Heilongjiang Province and composed of deep oceanic sediments and mafic igneous rocks, was considered as slice of oceanic crust and intruded by Hamahe and Taipingcun granites. Zircon U-Pb dating indicated that both of plutons were emplaced in Early Cretaceous, with the Hamahe pluton formed at three individual stages (131Ma, 124Ma and 115Ma, respectively) and the Taipingcun pluton at 111 similar to 114Ma. However, the gabbro in Raohe Complex was formed at 166 +/- 1Ma, and the latest radiolarian in the deep oceanic sediments is about 160 similar to 150Ma. Therefore, it is concluded that the emplacement of the Raohe Complex took place at 150 similar to 131Ma of Late Jurassic-Early Cretaceous, indicating that there existed the Pacific plate subduction and striking-slip in this area before and during Late Jurassic-Early Cretaceous. Petrological studies indicate that both plutons contained magmatic cordierites and show peraluninous characteristics, suggesting their S-type affinity derived from partial melting of the sedimentary rocks. Hf isotopic analyses show that the zircons from plutons have,e high Hf-116/Hf-177 ratios and positive epsilon(Hf)(t) values, and the Hf isotope model age with the felsic crust rocks is 500 similar to 780Ma, which indicates that their protolith Should be the juvenile crust formed in Neo Proterozoic-Phanerozoic. Therefore, it is Suggested that there existed significant crust uplift and weathering before Late Jurassic-Early Cretaceous in the area. |
