| 英文摘要 | Recent discoveries of rare metal pegmatite deposits in the West Kunlun region are believed to be related to Triassic granites. However, the tectonic background of the mineralization in this region is currently unclear. Additionally, the mineralization potential of the granite must be determined to assess whether further exploration is warranted. This paper reports whole-rock elemental and Sr-Nd isotopic compositions, and zircon U-Pb ages and Lu-Hf isotopic compositions for the Habake granitic pluton. The zircon U-Pb dating revealed that these rocks formed in the Late Triassic (210-205 Ma). The two-mica granites are strongly peraluminous high-K calc-alkaline series rocks, with initial Sr-87/Sr-86 ratios of 0.71294 similar to 0.71428, epsilon Nd(t) values of -7.79 similar to -8.15, and epsilon Hf(t) values of -1.77 similar to -32.22; these values are similar to those of Triassic BaryanHar Group graywacke rocks. The other granites are weakly peraluminous high-K calc-alkaline series rocks, with initial Sr-87/Sr-86 ratios of 0.70820 similar to 0.70823 and 0.70942 similar to 0.71041, epsilon Nd(t) of -3.81 similar to -4.11 and -5.33 similar to -5.40, and epsilon Hf(t) of -0.90 to +7.02 and -1.39 to -7.68, indicating that the granodiorite and biotite granite were respectively derived from partial melting of the juvenile crust and older lower crust in continental collision stage. Our new data show that the end of the continental collision between the South Kunlun Terrane (SKT) and Tianshuihai terrane (TST) likely occurred after 209 Ma. After analysis of the ore-forming parent rocks of the rare metal pegmatites, the graywacke-derived Habake two-mica granites, has lower Li contents that too low(<150 ppm), indicating that they did not form the rare metal pegmatites. |
