“…For example, Zhang et al (2013Zhang et al ( , 2020 the northern Alxa region and suggested that this intracontinental deformation resulted from the far-field effect associated with the collision between the Eurasia and different indenters including the Bayan Har Terrane and Yangtz Craton during the Late Triassic. And the study of the Triassic sedimentary provenance in the southern Junggar Basin also suggested that the Late Triassic uplift of the Bogda Mountains resulted from the far field effect of the Qiangtang-Eurasia collision (Wang et al, 2021). Therefore, we proposed that the Late Triassic intracontinental deformation in the Tianshan range is more likely to be related to far-field effects.…”

The Tianshan range, a Paleozoic orogenic belt in Central Asia, has undergone multiple phases of tectonic activities characterized by the N‐S compression after the early Mesozoic, including the far‐field effects of the Cenozoic Indian‐Asian collision. However, there are limited reports on the tectonic deformation and initiation of Triassic intracontinental deformation in the Tianshan range. Understanding this structural context is crucial for interpreting the early intracontinental deformation history of the Eurasian continent during the early Mesozoic. Growth strata and syn‐tectonic sediments provide a rich source of information on tectonic activities and have been extensively used in the studies of orogenic belts. Based on detail fieldwork conducted in this study, the middle‐late Triassic Kelamayi Formation of the northern Kuqa Depression in the southern Tianshan fold‐thrust belt has been identified as the typical syn‐tectonic growth strata. The youngest detrital zircon component in two lithic sandstone samples from the bottom and top of the Kelamayi growth strata yielded U‐Pb ages of 223.4 ± 3.1 and 215.5 ± 2.9 Ma, respectively, indicating that the maximum depositional age of the bottom and top of the Kelamayi growth strata is 226‐220 and 218‐212 Ma. The geochronological distribution of detrital samples from the Early‐Middle Triassic and Late Triassic revealed abrupt changes, suggesting a new source supply resulting from tectonic activation in the Tianshan range. The coupling relationship between the syn‐tectonic sedimentation of the Kelamayi Formation and the South Tianshan fold‐thrust system provides robust evidence that the Triassic intracontinental deformation of the South Tianshan range began at approximately 226‐220 Ma (during the Late Triassic) and ended at approximately 218‐212 Ma. These findings provide crucial constraints for understanding the intraplate deformation in the Tianshan range during the Triassic.

“…Zircon crystallisation ages are reported in Table S2. Following previous authors (Baesso et al, 2021; Markwitz et al, 2017; Olierook et al, 2019; Philipp et al, 2021; Wang et al, 2021), ages with discordance >10% were discarded (n = 17). We used the 206 Pb/ 238 U age to date the zircons younger than 1.3 Ga and the 206 Pb/ 207 Pb age for the zircons older than 1.2 Ga, in agreement with Gehrels et al (2008).…”

“…Provenance analysis aims at locating the source areas of detrital sediments based on a wide range of petrological evidence (Boggs Jr, 2009). Over the past decade, provenance analysis of heavy minerals has emerged as a powerful tool for reconstructing the tectono‐sedimentary evolution of rift basins (Baesso et al, 2021; Hart et al, 2016; Olierook et al, 2019; Wang et al, 2021). So far, the scarcity of coarse detrital material precluded a provenance analysis of pre‐break‐up deposits of the Demerara Plateau.…”

Thermochronology and U–Pb dating of detrital zircons from the Demerara Plateau (French Guiana‐Suriname): Implications for the provenance of the Early Cretaceous syn‐rift sedimentation

The provenance of Early Cretaceous sandstones dredged on the northern margin of the Demerara Plateau, offshore French Guiana and Suriname, reveals the sediment routing system that prevailed through the Equatorial Atlantic rifting. Fission‐track analysis and U–Pb dating of 310 and 111 detrital zircons, respectively, have been performed. Microfacies analysis and inherited cooling ages suggest that the sandstones were deposited in shallow marine environments during the Early Cretaceous, before the Late Albian drowning of the marginal plateau. Most of the U–Pb zircon crystallisation ages are comprised of between 700 and 600 Ma and are attributed to the Pan‐African‐Brasiliano orogeny. Statistical and chronological evidence suggest that the zircon fission‐track cooling ages were inherited from source materials. Triassic peak ages (>50% of the population) are attributed to the early phase of Central Atlantic rifting. One sample records a cooling phase at ca. 170 Ma, presumably following volcanic hotspot activity and the opening of the Central Atlantic Ocean. Two other samples record the rapid exhumation of the French Guiana transform margin during the Equatorial Atlantic rifting (127 ± 11 and 106 ± 8 Ma). We propose a source‐to‐sink model in which the Pan‐African‐Brasiliano basement of the margin was eroded as a result of flexural uplift along the French Guiana margin, and the detrital material funnelled in the Cacipore graben sustained the Early Cretaceous syn‐rift sedimentation on the marginal plateau.

“…From the detrital zircon age study of samples from the central TB, we found that multiple provenances supplied weathered source rocks, and due to the overlap of detrital zircon ages from the basin boundary mountains, there are multiple solutions, and the primary and secondary relationships of the source supply are difficult to determine. Thus, geochronology (J. Wang et al, 2021), palaeocurrents (Lin, 1994), petrology (Greene et al, 2005) and heavy minerals (J. Zhang et al, 2020) are further used in the study of some strata source‐to‐sink systems in the TS area. Here, we mainly focus on the application of heavy minerals collected from wells in Jurassic strata to further constrain the provenances (Figure 4).…”

Source‐to‐sink system studies in oil fields are especially important for optimizing the favourable oil‐gas areas; however, this basin‐mountain interaction process is particularly complicated in intermontane basins. In this study, detrital zircon U–Pb dating of 8 new and 3 published samples from throughout the Jurassic in the central Turpan Basin (TB) are combined with collected heavy mineral data to investigate the evolution of the source‐to‐sink system and reconstruct the filling process of this intermontane basin from the Lower to Upper Jurassic. Based on the detrital zircon ages and heavy mineral assemblage, the filling rocks mainly weathered from Mesozoic, Palaeozoic and Precambrian volcanic and metamorphic rocks in the Tian Shan (TS) area, and the source‐to‐sink systems in the basin show a clear alteration corresponding to the uplift of the surrounding mountains during the Jurassic. In the Lower Jurassic, the uplifted central and northern TS was the main provenance and shed the most source rocks northward, and the gentle positive relief of the Bogda Mountains (BM), the northern boundary of the TB, was a secondary provenance and provided limited material to the northern area. In the early Middle Jurassic, these provenances did not alter much, but in the later Middle Jurassic, uplift of the western BM began and provided some extreme new source rocks with detrital zircon ages of approximately 159–172 Ma. In the Upper Jurassic, the considerably uplifted BM became the main provenance, while the still gently uplifted central and northern TS became the secondary provenance.
