英文摘要The question of whether the Junggar terrane in the central area of the Central Asian Orogenic Belt (CAOB) has a Precambrian basement is one of the hottest topics surrounding the tectonic evolution of the CAOB. Recent work shows that the Central Tianshan range has a Mesoproterozoic-Neoproterozoic basement Here, we reported the SIMS U-Pb age and Hf isotopes of zircons from newly discovered dioritic gneiss and magnetite quartzite enclaves and their host diorite dike in the Taheir area, deformed Ordovician conglomerate in the Dazigou area, and mica gneiss relicts and their host granite in the Shuangchagou area in the Junggar terrane. The results reveal the following evidence: 1) the dioritic gneiss was metamorphosed from 2.52 Ga diorite at approximately 1.88 Ga, the magnetite quartzite interlayered with hornblende-plagioclase gneiss layers has an age of approximately 1.92 Ga, and the inherited zircons from the diorite TH4-6 contain three zircon populations with upper intercept ages of approximately 3.06 Ga, 1.98 Ga and 1.89 Ga; 2) the sienna and colorless zircon populations from the conglomerate reveal two magmatic rocks with ages of approximately 1.86 Ga and 0.94 Ga; and 3) the magmatic zircons that form mica gneiss have T-DMC and T-DM2 ages ranging from 1.2 Ga to 2.08 Ga, and the inherited zircons from the mica gneiss and granite in the Shuangchagou area contain five zircon populations with upper intercept ages of approximately 2.48 Ga, 1.80 Ga, 1.47 Ga, 1.14 Ga and 0.96 Ga.
