“…The external precision was determined by measurements of the GSB-Mg and USGS basalt standards (BCR-2 and BHVO-2). The δ 26 Mg value of GSB-Mg (−2.03 ± 0.03‰; 2σ), BCR-2 (−0.16 ± 0.05‰; 2σ) and BHVO-2 (−0.25 ± 0.04‰; 2σ) are consistent with the laboratory recommended values or previously published data [49][50][51][52]55 .…”

“…In fact, different studies show that carbonates from the Central Paratethys during Miocene have similar δ 18 O as that of the Anjihaihe dolomite, which reflect the oxygen isotope composition of the Paratethys seawater [46][47][48] . Moreover, a paleo-valley system existed among the Tianshan Mountains during the Late Cretaceous to the early Miocene before the uplift of the Tianshan Mountains 49 , which could have connected the Junggar Basin to the Paratethys Sea, even just intermittently.…”

The Cenozoic retreat of the Paratethys Sea, as well as uplift of the Tibet plateau and global cooling, have been considered as the main mechanisms for the onset of the Asian monsoon. However, due to the weak constraints on the time and path of the Paratethys Sea, the relative contribution of each of the three factors to the onset of the Asian monsoon remains debatable. Previous studies on the retreat process of the Paratethys suggested that its east coastline had already withdrawn from the Chinese Tianshan area to the west by the Oligocene. Here, we provide a new perspective on this discussion through the study of the Oligocene Anjihaihe dolomite from the northern Chinese Tianshan. Through the comparisons of carbon, oxygen, magnesium, and strontium isotope compositions between the dolomite beds and their interlayered precursor lacustrine limestone beds, we show that the Anjihaihe dolomites were formed at the end of the Oligocene from dolomitization by a fluid characterized by high δ18O, low δ26Mg, low temperature, relatively poor in carbon and Sr. This fluid was likely derived from seawater from the close-by Paratethys Sea at the time. This discovery suggests a larger Paratethys Sea during the Oligocene than previously thought and may have important implications to understand the evolution of the palaeogeography in the Chinese Tianshan region and the onset of the Asian monsoon.

“…Although the Tian Shan and its adjacent areas were suggested to be a peneplain in the Early Jurassic (Jolivet et al, ), the Bogda and Harlik areas probably had a gentle positive relief and provided material to the intermontane regions adjacent to both sides of the Bogda mountains (Fang et al, ; Ji et al, ; Tang et al, ; Yang et al, ). During the Middle to Late Jurassic, episodic volcanism occurred at the southern margin of the Junggar basin, along the northern flank of the NTS (Yang et al, ).…”

“…How the current tremendous relief formed from the planation surface in the Jurassic is widely debated in the geological study of the Tian Shan region. Some studies have suggested that the topography during the Jurassic was not totally flat everywhere, with gentle relief at some places in the northern and central Tian Shan (Fang et al, ; Ji et al, ; Tang et al, ; Yang et al, ), whereas Jolivet et al () proposed that this gentle relief was not established until the Oligocene.…”

Detrital zircon geochronology analysis of the Late Mesozoic deposition in the Turpan‐Hami basin: Implications for the uplift history of the Eastern Tian Shan, north‐western China

Analysing the provenance changes of synorogenic sediments in the Turpan‐Hami basin by detrital zircon geochronology is an efficient tool to examine the uplift and erosion history of the easternmost Tian Shan. We present detrital zircon U‐Pb analysis from nine samples that were collected within marginal lacustrine Middle‐Late Jurassic and aeolian‐fluvial Early Cretaceous strata in the basin. Middle‐Early Jurassic (159–172 Ma) zircons deriving from the southern Junggar dominated the Middle Jurassic sample from the western Turpan‐Hami basin, whereas Permian‐Carboniferous (270–330 Ma) zircons from the Bogda mountains were dominant in the Late Jurassic to Early Cretaceous samples. Devonian‐Silurian (400–420 Ma) and Triassic (235–259 Ma) zircons from the Jueluotage and Harlik mountains constituted the subordinate age groups in the Late Jurassic and Early Cretaceous samples from the eastern basin respectively. These provenance transitions provide evidence for uplift of the Bogda mountains in the Late Jurassic and the Harlik mountains since the Early Cretaceous.

In Central Asia, numerous fragments of planation surfaces are visible within the present day topography. However, their precise timing of formations is still poorly constrained and it is not clear if they are remnants of a single extensive planation surface or if they represent different planation episodes. By reconstructing the landscape evolution of the Tian Shan region and by analyzing the relations between the planation surfaces preserved within the eastern Tarim Basin and the sedimentary record, we demonstrate that the numerous erosional surfaces preserved within the Tian Shan Range represent different episodes of surfaces genesis. These erosion events span from the late Paleozoic to the Early Cenozoic. The widespread preservation of large fragments of these surfaces within the Tian Shan Range implies that this region did not undergo strong relief building during most of its Mesozoic evolution but was dominated by plains associated to small hills along episodically active discrete tectonic structures. Finally, the preservation of these surfaces within the active Tian Shan Range implies a long-term, strong non-equilibrium state of the topography during its Cenozoic evolution. This was probably promoted by the arid to semi-arid climate prevailing since the Late Paleogene onset of relief building.
