“…Integrated analyses of the Mesozoic–Cenozoic depositional systems, sandstone framework grains, detrital heavy minerals and whole sandstones geochemical compositions from the Kuqa Subbasin (Li et al , 2004, 2005) suggest that the depositional evolution in the Subbasin underwent five discontinuous phases. These phases are divided by four boundaries at Early Triassic\Middle Triassic, Middle–Late Jurassic\Early Cretaceous, Cretaceous\Paleogene and Paleogene\Neogene time (Fig.…”

Previously published research from the Kuqa Subbasin along northern margin of theTarim Basin shows ¢ve tectonic-depositional phases from Triassic to Neogene time. In order to reveal additional detailed information on the nature of provenance terrains and tectonic attributes since late Mesozoic time, ¢ve typical sandstone samples from Jurassic^Neogene strata were collected for U^Pb dating of detrital zircons. Geochronological constitution of detrital zircons of the Middle Jurassic sample is essentially unimodal and indicates major contributions from the South Tian Shan even Yili^Central Tian Shan, wherein most 370^450 Ma zircons probably resulted from tectonic accretion events between the Yili^Central Tian Shan block and South Tian Shan Ocean during Silurian and Devonian time, with sandstone provenance tectonic attributes of passive continental margin.The Lower Cretaceous sample shows a complicated provenance detrital zircon signature, with new peak ages of 290^330 Ma as well as 370(or 350)^450 Ma showing evident arc orogenic provenance tectonic attribute, probably re£ecting a new provenance supply that resulted from denudation process whthin the South Tian Shan and South Tian Shan suture.There are no obvious changes within age probability spectra of detrital zircons between the Cretaceous and early Paleogene samples, which suggests that similar provenance types and basin-range framework continued from Cretaceous to Early Paleogene time. However, unlike the Cretaceous and early Paleogene samples, an age spectra of the Miocene sample is relatively unimodal and similar to that of the Pliocene sample, with peak ages ranging between 392 and 458 Ma older than the comparable provenance ages (peak ages about 370^450 Ma) of the Middle Jurassic and Lower Cretaceous samples.Therefore, we conclude that the South Tian Shan was rapidly exhumated and the southern South Tian Shan had become the main source of clastics for the Kuqa Subbasin since the Miocene epoch.

“…Previous studies have primarily concentrated on the Palaeozoic amalgamation history (e.g., Abzalov, ; Biske & Seltmann, ; Gao et al, ; Gao, John, Klemd, & Xiong, ) and Cenozoic deformation (e.g., Graham, Hendrix, Wang, & Carroll, ; Hendrix, ; Hendrix et al, ; Lin et al, ; Lu et al, ; Sobel, ), and relatively little attention has been paid to the Mesozoic. A major period of tectono‐magmatic quiescence was recognized during the Triassic and Jurassic times (Dumitru et al, ; Han, He, Wang, & Guo, ; Jolivet et al, ), and renewed tectonic uplifting occurred in late Mesozoic, especially in the Late Jurassic–Early Cretaceous period, as demonstrated by sedimentological and structural studies in the Junggar Basin (Jolivet, Bourquin, & Heilbronn, ; Yang et al, ) and Kuqa Sub‐basin of the Tarim Basin (Dumitru et al, ; Li et al, ; Li, Song, Peng, Wang, & Zhang, ), which flank the western Tianshan Orogen on the north and south. However, the Late Jurassic–Early Cretaceous reactivation may have been caused by far‐field geodynamic processes of either the closure of the Mongol–Okhotsk Ocean (Jolivet et al, ) or the collision of the Karakoram–Lhasa Block with the southern Asian margin (Hendrix et al, ; Sobel, ), because the Mongol–Okhotsk Ocean mainly closed on a relative short time scale (10 Ma) around the latest Jurassic–earliest Cretaceous transition (Nachtergaele et al, ; Wilhem, Windley, & Stamp, ; Yang, Guo, Song, Li, & He, ), which almost overlaps with the collision of Karakoram–Lhasa Block from late Middle Jurassic to Early Cretaceous (Li et al, ; Yang, Guo, & Luo, ).…”

“…The western Tianshan Orogen extends east–west for 2,500 km through western China, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan in central Asia, with the highest peak up to 7,400 m (Allen & Windley, ; Jia, Fu, Jolivet, & Zheng, ). As an important segment of the Central Asian Orogenic Belt, the western Tianshan Orogen has experienced multiple accretions of island arcs and amalgamations of different continental blocks during the Palaeozoic (Charvet et al, ; Glorie et al, ; Windley, Alexeiev, Xiao, Kröner, & Badarch, ) and complex intracontinental structural reactivations during the Meso‐Cenozoic period, which controlled coeval basin‐range evolution and surface process (Li, Guo, Wang, & Lin, ; Li & Peng, ). Previous studies have primarily concentrated on the Palaeozoic amalgamation history (e.g., Abzalov, ; Biske & Seltmann, ; Gao et al, ; Gao, John, Klemd, & Xiong, ) and Cenozoic deformation (e.g., Graham, Hendrix, Wang, & Carroll, ; Hendrix, ; Hendrix et al, ; Lin et al, ; Lu et al, ; Sobel, ), and relatively little attention has been paid to the Mesozoic.…”

Provenance of the uppermost clastic rocks of the Lower Cretaceous Kezilesu Group from the Ulugqat Basin, Xinjiang, NW China and its tectonic implications: Insights from sedimentary records and detrital zircon U–Pb geochronology

The Ulugqat Basin is located at the juncture of the Tarim Basin, the western Tianshan Orogen of the Central Asian Orogenic Belt, and the Pamir salient of the Tethys domain. A comprehensive provenance study using sedimentology, petrology, and detrital zircon U–Pb geochronology was carried out on the clastic rocks of the fifth member of the Lower Cretaceous Kezilesu Group from the Ulugqat Basin, aiming to better understand the nature of its relationships with the neighbouring tectonic units as well as the formation of sandstone‐hosted Zn–Pb mineralization. The fifth member consists of conglomerate, gravelly sandstone, sandstone, and mudstone interbeds, and is interpreted as alluvial fan–braid river–braid river delta sediments. The conglomerate and gravelly sandstone contain different kinds of lithic fragments, including phyllite, quartzite, chert, chalcedony, and some felsic igneous rocks, with low compositional maturities. The detrital zircon U–Pb ages of sandstone from the uppermost part of the fifth member range widely from 229.7 to 2,984.9 Ma, concentratedly distributed in five groups: 230–300, 390–480, 750–880, 1,600–2,200, and 2,300–3,000 Ma. The identified palaeocurrent directions, heavy mineral assemblages, specific provenance indicators, and distributions of detrital zircon U–Pb ages all indicate that these clastic rocks are probably sourced from the South Tianshan Orogen to the north, rather than the Pamir salient, probably involving the Proterozoic Aksu metamorphic rocks, Palaeozoic sedimentary rocks, Late Carboniferous–Early Permian alkali granite, and some mafic/ultramafic rocks of ophiolitic mélange. This interpretation is consistent with a late Early Cretaceous uplifting of the South Tianshan Orogen according to previous low‐temperature thermochronological data sets. The thick deposition of these Lower Cretaceous clastic rocks and associated uplifting of the South Tianshan Orogen are interpreted to be related to the coeval collision of the Karakoram–Lhasa Block with the southern Asian margin.

The Kuqa Depression is an important oil and gas exploration area in the Tarim Basin, and exploration practices indicate that the gas reservoirs such as Dabei, Kela, and Keshenare distributed in the Cretaceous palaeo-uplift area. However, few studies have been done on the Cretaceous palaeo-uplifts. On the basis of the logging gamma curve, the spectrum analysis of the Bashijiqike Formation shows that the sedimentation of the Lower Cretaceous stratum was controlled by the Milankovitch cycles. As the stratum exhibits the characteristic Milankovitch periodicities, 133, 124, 100, and 95 ka eccentricity, 46.5 and 36.6 ka obliquity, and 22.2 ka precession periods are identified in the residual Bashijiqike Formation. By combining the results of cyclic analysis and thermal simulation of apatite fission track (AFT), the stratum denudation amount of Dabei-Tubei palaeo-uplift and Kelasu palaeo-uplift in the Late Cretaceous was calculated, and the palaeo-uplifts were restored. The results show that the original thickness of the Cretaceous stratum in the core of the Dabei-Tubei palaeo-uplift was 1,500 m and was more than 1,800 m in the core of the Kelasu palaeo-uplift. The AFT modelling results indicate that there were two cooling phases in provenance, that is, since the Late Triassic-Early Jurassic (ca. 200 Ma) and the Late Jurassic-Early Cretaceous (ca. 160-130 Ma). In addition, the depositional area also experienced two cooling phases, namely, since the Late Cretaceous (ca. 110-60 Ma) and the Late Palaeogene-Early Neogene (ca. 20 Ma).
