“…The Ulugqat Basin is a typical Meso‐Cenozoic intracontinental sub‐basin in the westernmost part of the southwestern Tarim Basin, west to the large‐scale Talas–Fergana strike‐slip fault (Figure 1b; Fang, Ma, Wang, Zhao, & Hu, ; Xue, Chi, Li, & Dong, ; Zhou, Luo, & Mai, ), and its formation and evolution were controlled by the South Tianshan Orogen to the north, the Pamir salient to the south, and the Talas–Fergana Fault (Figure ; Wang, Hu, & Liu, ; Zhou et al, ). The Ulugqat Basin contains a thick section of Jurassic–Quaternary sedimentary series overlying the Palaeozoic sedimentary rocks that rest on a Precambrian metamorphic basement (Figure 3a; Xue et al, ). The basement is characterized by schist, phyllite, quartzite, marble, and meta‐ironstones of the Proterozoic Akesu Group (BGMRXJ, ; Liu et al, , ).…”

“…820–750 Ma (Yong et al, ; Zhang et al, ). The Lower Palaeozoic sedimentary rocks were deposited in a passive margin related to the South Tianshan Ocean, whereas the upper Palaeozoic sedimentary sequences were developed in foreland basins following the closure of the ocean (Wang et al, ; Xue et al, ; Zhou et al, ). A detailed stratigraphic and lithologic summary of Jurassic–Quaternary sedimentary sequences is presented in Figure .…”

“…Based on the difference of petrographic composition and internal structure, the K 1 kz can be divided into five members from bottom to top (K 1 kz 1 to K 1 kz 5 ) in the Uragen area (Liu et al, ; Xue et al, ). The first member (K 1 kz 1 ) is composed of brown‐red (locally grey‐green) basal conglomerate, conglomerate, pebbly sandstone, and mudstone/sandstone interbeds.…”

“…A variety of Precambrian plutons have been dated, and the U-Pb ages of these plutons can be divided into four groups 140,1,020,and 2,550 Ma), corresponding to four main tectono-thermal events, namely, the breakup and amalgamation of the Rodinia supercontinent, amalgamation of the Columbia supercontinent, and global continent-building event (e.g., Liu, Jolivet, et al, 2013;Shu, Deng, Zhu, Ma, & Xiao, 2011). Fang, Ma, Wang, Zhao, & Hu, 2009;Xue, Chi, Li, & Dong, 2014;Zhou, Luo, & Mai, 2005), and its formation and evolution were controlled by the South Tianshan Orogen to the north, the Pamir salient to the south, and the Talas-Fergana Fault (Figure 3; Wang, Hu, & Liu, 2003;Zhou et al, 2005).

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 Pamir‐Tian Shan collision zone in the western Tarim Basin, northwest China, formed from rapid and ongoing convergence in response to the Indo‐Eurasian collision. The arid landscape preserves suites of fluvial terraces crossing structures active since the late Neogene that create fault and fold scarps recording Quaternary deformation. Using geologic and geomorphic mapping, differential GPS surveys of deformed terraces, and optically stimulated luminescence dating, we create a synthesis of the active structures that delineate the timing, rate, and migration of Quaternary deformation during ongoing convergence. New deformation rates on eight faults and folds, when combined with previous studies, highlight the spatial and temporal patterns of deformation within the Pamir‐Tian Shan convergence zone during the Quaternary. Terraces spanning ~130 to ~8 ka record deformation rates between ~0.1 and 5.6 mm/yr on individual structures. In the westernmost Tarim Basin, where the Pamir and Tian Shan are already juxtaposed, the fastest rates occur on actively deforming structures at the interface of the Pamir‐Tian Shan orogens. Farther east, as the separation between the Pamir‐Tian Shan orogens increases, the deformation has not been concentrated on a single structure, but rather has been concurrently distributed across a zone of faults and folds in the Kashi‐Atushi fold‐and‐thrust belt and along the NE Pamir margin, where shortening rates vary on individual structures during the Quaternary. Although numerous structures accommodate the shortening and the locus of deformation shifts during the Quaternary, the total shortening across the western Tarim Basin has remained steady and approximately matches the current geodetic rate of 6–9 mm/yr.
