| 英文摘要 | Hf isotope measurement has been carried out for UHP metamorphic eclogite from Xindian by using LA-MC-ICP-MS technique. The result indicates that metamorphic growth zircon has high Hf-176/Hf-177 (0.282544-0.282612) and low Lu-176/Hf-177 (0.000004-0.000211) ratio, inherited and recrystallized protolith zircon has low Hf-176/Hf-177 (0.282266-0.282466) and high Lu-176/Hf-177 (0.000090-0.002144) compositions. The low Lu-176/Hf-177 of growth zircon comes from its decreasing of Lu and increasing of Hf during UHP process. The high Hf-176/Hf-177 deduced from high radiogenic Hf-176, which was produced from long-term evolution of high Lu/Hf ratio minerals. Partial recrystallization of protolith zircon would not cause reworking of Lu/Hf isotope in zircon. Compared to U-Pb, zircon Lu-Hf system has better stability. The initial Hf isotope composition of metamorphic growth zircon may represent the Hf isotope composition of whole rock system at the same time. The initial epsilon(Hf) of +3.0 for metamorphic precursor formation of Xindian eclogite indicates that the source material mainly derived from weak depleted mantle or mixing of depleted mantle with old crust. |
