| 英文摘要 | The temporal-spatial framework of arc amalgamation is an important key for understanding the anatomy of orogenic collages, present and past. The Junggar-Balkhash Ocean was a major branch of the southern Paleo-Asian Ocean where several arcs were amalgamated. Among them, the Dananhu arc with its characteristic juvenile magmatism and lack of Precambrian basement is an efficient recorder of the evolutional history. From our U-Pb and Lu-Hf isotopic analyses of Devonian to Triassic sediments in the Dananhu arc and Permian sediments in the Yamansu-Central Tianshan arc, we discovered two major changes in detrital zircon provenance of the Dananhu arc: (a) An increasing input of Precambrian ages from the Mongolia collage at 850, 1,850, and 2,500 Ma, together with Phanerozoic zircons ranging from 420 to 480 Ma with negative epsilon Hf(t) value since ca. 288 Ma; (b) the presence of the Yamansu-Central Tianshan arclike Precambrian age cluster of 1,400-1,600 Ma around 243 Ma. In combination with regional tectonothermal events, these two changes correspond to the formation of the Harlik-Dananhu composite arc in the latest Carboniferous-early Permian followed by its collision with the Yamansu-Central Tianshan arc in the latest Permian-early Triassic, which marks the termination of the eastern Junggar-Balkash Ocean. Analysis of the sedimentary successions within the intraoceanic arcs sheds light on the amalgamation history of the Central Asian Orogenic Belt. |
