Abstract	Frequent cloud cover leads to significant problems in estimating snow distribution based on remote-sensing observations, especially in mountainous regions. Supported by Google Earth Engine (GEE), a cloud-gap filling framework using the cubic spline interpolation method was proposed to generate cloud-free data based on the MODIS snow cover dataset. The framework is validated in the Chinese Tien Shan region with in-site snow depth observations, demonstrating good agreement. Subsequently, the spatio-temporal patterns and trends of snow cover in Chinese Tien Shan for nearly 20 years were identified using temporal interpolated snow cover data. The results show that (1) the interpolated images generated by the framework effectively fill the invalid value caused by cloud cover and have significant consistency with the snow depth data from gauges (with the Snow Cover Days (SCD) score of 0.89 and the correlation coefficient (CC) of 0.80); (2) compared with linear interpolation, the interpolated snow cover images generated based on cubic spline method have higher CC with snow depth data from gauges, reflecting higher data reliability; and (3) the snow cover over Chinese Tien Shan demonstrated remarkable periodicity and different spatial distribution, and it had an apparent decreasing trend in the southeastern region of Chinese Tien Shan.

Abstract	River piracy has been reported worldwide and was regarded as one of the main drivers for landscape evolution. In this study, we introduce an example of river piracy in the northern Qilian Shan (northeastern Qinghai-Tibet Plateau), and further interpret its regional geomorphological implications. Chi-map analysis, erosion potentiality evaluation, and river profile inversion are used to verify the river piracy. The results confirm that the transverse river, the Hongshuiba River, has captured the longitudinal river, the Zhulongguan River at ~0.35 Ma, due to the headward-migrating erosion of the main stem of the Hongshuiba River. The drainage reorganization, with longitudinal rivers captured by transverse rivers, is a common and continuous landform process along with the outward growth of the northern Qilian Shan. Moreover, the present Qilian Shan watershed geomorphic system could be considered as a transient stage of drainage evolution during the mountain building.

Abstract	The source‐to‐sink relationship between a sedimentary basin and its adjacent mountain range is vital for understanding the genesis of piedmont coarse‐grained sediments and the evolution of mountain topography. By integrating zircon U‐Pb dating and heavy mineral assemblage analyses on 15 samples, this work focuses on the change of the provenance with time in the Urumqi River Neogene‐Pleistocene continental sequence in the northern Chinese Tian Shan foreland, which has been chronologically constrained to range from ∼6.8 to ∼0.55 Ma. The results of the integrated provenance analyses reveal two shifts in provenance during the periods of 4.6–2.5 and 0.9–0.55 Ma, yielding new zircon U‐Pb age signals from the glacier‐covered headwaters of the Urumqi River. These two identified provenance adjustments are causally related to enhanced glacial erosion in the high mountain. We propose that enhanced glacial erosion could have caused southward expansion of the Urumqi River drainage basin, increased production of coarse‐grained materials with new zircon U‐Pb age signals, and finally accumulation of piedmont alluvial gravel. The observed topographic and sedimentary responses to enhanced glaciation could have been common phenomena during the late Quaternary in alpine areas, where a large number of alluvial fans are widely distributed like aprons along the mountain front, as seen in the piedmonts of the Tian Shan in the arid interior of Asia.

Abstract	Surface erosion shapes the topography of an active orogenic belt with a rate depending on the time and space scales. Quantifying erosion rates over various temporal and spatial scales is thus crucial for understanding the topographic evolution in active orogenic belts. This work focused on the decadal catchment-basin erosion rate and its controlling factors in the northern Chinese Tian Shan. Nine mountainous catchment basins were selected to quantify the decadal-scale erosion rates from hydrological data measured during the years 1964–2011. The contributions of the suspended load, bed load, and solute load in the river sediment load were first determined. The erosion rate was then calculated for each analyzed catchment basin. The results show that the average rate of catchment-basin erosion is ∼ 0.15 mm yr⁻¹, whereas the rate varies from one catchment basin to the next (the minimum rate of 0.05 mm yr⁻¹ in the Urumqi and the maximum rate of 0.30 mm yr⁻¹ in the Manas). In order to explore the possible effects of climate, topography, lithology, vegetation, and tectonics on catchment-basin erosion, correlation analyses were conducted between these factors and the erosion rate. The results indicate that the catchment-basin erosion rate is more closely correlated with topographic factors (basin area and basin relief) and climatic variables (discharge, run off, run off depth, and mean temperature), indicative of the main controlling of topography and climate on catchment-basin erosion. The erosion rates reported in this work are approximately consistent with the paleo-erosion rate of < 0.5 mm yr⁻¹ over the last 1.5 Myr derived from in situ produced cosmogenic ¹⁰Be concentrations in the Kuitun catchment basin in the west part of the range. Such a consistency is likely to imply relatively stable erosion during the late Quaternary in the northern Chinese Tian Shan.

Article: 10Be dating of the Kuitun River terraces in the northern Chinese Tian Shan foreland: Insights into fluvial evolution and tectonic shortening pattern

Abstract	Characterizing active deformation of a piedmont structure is particularly helpful for understanding the dynamics of deformation of its adjacent active orogenic belt. This work focuses on fluvial geomorphology of the Kuitun River, which flows northwards out of the high mountains and perpendicularly cuts the E-W-striking Dushanzi anticline, a structure of the outermost fold-and-thrust belt in the northern Chinese Tian Shan foreland. Four episodes of alluvial fan development (fans F₁–F₄, sequentially younger in abandonment age) were identified. Based on the fluvial geomorphological framework constructed by these four alluvial fans, six terraces (terraces T₁–T₆, sequentially increasing height above the riverbed) were then defined. The topographic analyses and ¹⁰Be dating of these alluvial landforms show that the Kuitun River originally flowed northwestwards before at least 80 ka. Subsequent rock uplift caused by fold growth could have resulted in an eastward deflection, after which the river began to flow northeastwards to construct fan F₂. At ~67 ka, accumulation of fan F₂ ended, and the Kuitun River deflected westwards to flow northwards and began to construct fan F₃. The final stabilization of the Kuitun River channel occurred at ~13 ka due to intense river incision forced by climate change, when the river began to incise a 200-m deep canyon and form a flight of strath terraces flanking the valley. By using geomorphic surfaces as the references, the Late Pleistocene and Holocene shortening rates of the Dushanzi anticline were estimated to be 0.71 + 0.17/−0.16 mm/yr (over the past ~67 kyr) and 1.6 + 0.39/−0.37 mm/yr (over the past 13 kyr), respectively. When combined with the long-term shortening rate of ~0.44 mm/yr since initiation of fold growth, it is inferred that the Dushanzi anticline likely experienced an acceleration of deformation during the late Quaternary. With respect to the entire orogenic belt, both fluvial geomorphic records and GPS surveys indicate that most of N-S crustal shortening (likely >70%) across the Tian Shan has been absorbed in the piedmonts of the range, a typical active orogenic belt in the interior of Asia.

Article: Dynamic Divide Migration as a Response to Asymmetric Uplift: An Example from the Zhongtiao Shan, North China

Abstract	Previous numerical–analytical approaches have suggested that the main range divide prefers to migrate towards the high uplift flank in the asymmetric tectonic uplift pattern. However, natural examples recording these processes and further verifying the numerical simulations results, are still lacking. In this study, the landscape features, and the probable drainage evolution history of the Zhongtiao Shan, a roughly west-east trending, half-horst block on the southernmost tip of the Shanxi Graben System, were investigated through the geomorphic analyses (i.e., slope and steepness distributions, and the Gilbert and χ metrics). The topographic slope and steepness results indicate that the Zhongtiao Shan, controlled by the north Zhongtiao Shan normal fault, experiences asymmetric uplift and erosion patterns, with higher uplift and erosion on the north range. In addition, the Gilbert and χ metrics suggest that the western part of the main divide is currently stable, while the eastern divide is moving southward. According to the drainage divide stability criteria, we suggest that the uplift and erosion, on the fault side, balance each other well on the western part of the range, while on the eastern part, the uplift is outpaced by the erosion. In addition, a dynamic divide migration model in the asymmetric uplift condition is proposed, indicating that the interaction between uplift and erosion controls the migration and/or stability of the main divide. Deducing through this dynamic model, we suggested that the eastern segment of the north Zhongtiaoshan Fault must have experienced higher activities in the geological history, and the western fault may remain its activity along with the mountain relief generation. This gives a case that specific information on asymmetric neotectonic history and landscape evolution in an orogenic mountain can be uncovered by the proposed dynamic model.

Abstract	The Tarim Basin, located in the rain shadow of the Tibetan Plateau and other central Asian active orogens, is one of the most arid areas in the mid-latitude of the Northern Hemisphere. Its aridification history is important for understanding climate changes in the context of global cooling and regional tectonics. In this study, we present an environmental magnetism study of the early Miocene-early Pliocene (~20–4 Ma) terrestrial sediments in the Southern Tian Shan foreland. Magnetic parameters representing the relative/absolute concentrations of hematite in the sediments, together with color parameters, are used to reconstruct the Neogene climate evolution of the Tarim Basin. Our results reveal that the Tarim Basin was dominated by relative warm and wet climate between ~17 Ma and ~14 Ma, corresponding to the Mid-Miocene Climatic Optimum (MMCO), followed by three stepwise cooling/drying events at ~14 Ma, ~7 Ma and ~5.3 Ma, respectively. The dramatic cooling event at ~14 Ma is attributed to the expansion of East Antarctic Ice Sheet. The stepwise aridification at ~7 Ma and ~5.3 Ma in the Tarim Basin was controlled first-order by global cooling but superimposed by regional tectonics. The late Miocene aridification at ~7 Ma is partly due to the reduced moisture transport to the Tarim Basin related to the Mediterranean Salinity. Basin-wide extreme aridification since ~5.3 Ma is dominated by the final collision between Pamir and Tian Shan, which blocked the water-vapor brought by the westerlies from the Paratethys Sea to the downwind Tarim Basin.
