英文摘要	Figuring out whether the sedimentary provenance regions of the thick deep-water turbidite systems deposited during Middle-Upper Ordovician in South Quruqtagh are the intracontinental uplifts or the peripheral orogenic belts is of great significance for us to understand the tectono-sedimentary nature of the northeastern Tarim Basin and basin-range coupling processes in the middle Paleozoic. This paper reports the in situ LA-ICP-MS U-Pb ages and Hf isotope data on detrital zircons from two Middle-Upper Ordovician sandstone samples which were collected from the Charchag Formation and the Zatupo Formation in South Quruqtagh, respectively. The results show that the studied two samples have extremely similar U-Pb age patterns and Hf isotopic compositions, reflecting multiphase tectono-thermal events with age groups of 527-694, 713-870 Ma (peaking at 760 Ma), 904-1,090, 1,787-2,094 Ma (peaking at 1,975 Ma) and 2,419-2,517 Ma. Combining previous studies, the presence of age groups of 713-1,090 and 1,787-2,094 Ma, respectively, demonstrates that Tarim had ever been a part of Rodinia and Columbia supercontinent. Moreover, 98 % of 713-870 Ma detrital zircons are characterized by negative epsilon (Hf) (t) values ranging from -38.07 to -0.61, which are highly consistent with those of Neoproterozoic granites from the Quruqtagh area. No Early Paleozoic ages (similar to 470-500 Ma) signifying subduction or collision events in Altyn Tagh were detected in the two samples, indicating that the Middle-Late Ordovician sediments in South Quruqtagh and northern Mangar depression were mainly derived from intracontinental uplifts, i.e., the North Quruqtagh uplift or the Tabei paleo-uplift, rather than the Altyn Tagh. In conjunction with regional sedimentary-tectonic background and previous studies, we proposed preliminarily that the northeastern Tarim remained as a passive continental margin in Late Ordovician and changed into an active-continental margin in Silurian due to the southward subduction of the South-Tianshan Ocean.
