Latest Permian–early Triassic arc amalgamation of the Eastern Tianshan (NW China): Constraints from detrital zircons and Hf isotopes of Devonian–Triassic sediments
Popis výsledku v původním jazyce
The temporal–spatial framework of arc amalgamation is an important key for understandingthe anatomy of orogenic collages, present and past. The Junggar‐BalkhashOcean was a major branch of the southern Paleo‐Asian Ocean where several arcswere amalgamated. Among them, the Dananhu arc with its characteristic juvenilemagmatism and lack of Precambrian basement is an efficient recorder of theevolutional history. From our U–Pb and Lu–Hf isotopic analyses of Devonian to Triassicsediments in the Dananhu arc and Permian sediments in the Yamansu‐CentralTianshan arc, we discovered two major changes in detrital zircon provenance of theDananhu arc: (a) An increasing input of Precambrian ages from the Mongolia collageat 850, 1,850, and 2,500 Ma, together with Phanerozoic zircons ranging from 420 to480 Ma with negative epsilonHf(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 correspondto the formation of the Harlik‐Dananhu composite arc in the latest Carboniferous–early Permian followed by its collision with the Yamansu‐Central Tianshan arc inthe latest Permian–early Triassic, which marks the termination of the easternJunggar‐Balkash Ocean. Analysis of the sedimentary successions within theintraoceanic arcs sheds light on the amalgamation history of the Central AsianOrogenic Belt.
