| 英文摘要 | An at least 60km long and 25km similar to 3km wide eclogite belt was recently discovered in the Lhasa block, which is located near Sumdo village about 200km east of the Lhasa city, Tibet. The Lu-Hf geochemical tracing and isotopic dating of zircons from the Sumdo eclogite gave a very even Lu-Hf isotopic composition and uniform age. All the zircons have the similar composition with higher Hf-176/Hf-177 (0.289651 similar to 0.2830295) and lower Lu-176/Hf-177 (0.000002 similar to 0.000008), which is probably related to its metamorphism and the formation of garnet during the metamorphism. The value of epsilon(Hf)(0) is between 6.8 and 10.0, which indicates that there is a significant input from the deplected mantle during the metamorphism. LA-ICPMS U-Pb dating of zircons from the eclogite yielded an average metamorphic age of 260 +/- 16Ma, indicating that there exist Permian HP/UHP(?) metamorphic belt in the Lhasa terrane. |
