“…Additionally, modern geodetic data reveal a potential 0.5 mm/a sinistral strike‐slip rate between the Huahai Basin and northern Tibetan Plateau (using GPS stations G138 and G127 data from M. Wang & Shen, 2020; Figure 2), which appears to be almost completely absorbed by active deformation in the northern Hexi Corridor, such as along the HF system. Synthesis of our structural observations, timing constraints and calculated fault slip rates with results from prior studies suggest that the eastern Heishan wrench fault/fold system and Jinta’Nanshan and Helishan deforming zones further east comprise a diachronously evolving sinistral transpressive belt along the northern Hexi Corridor (Pan et al., 2021; W. J. Zheng, Zhang, Ge, et al., 2013).…”

“…The Kuantanshan-Heishan-Helishan Mountains are relatively low-lying ranges at ∼2,600 m asl directly north of the northwestern Hexi Corridor basin (Figure 2). Prior research concerning the tectonic geomorphology and landscape evolution of these ranges has suggested that they were uplifted during 2∼0.6 Ma (Hetzel et al, 2004;Pan et al, 2021; W. J. Zheng, Zhang, Ge, et al, 2013).…”

The Altyn Tagh fault (ATF) is a major intracontinental strike‐slip fault system that defines the northern margin of the Tibetan Plateau. The fault system loses its obvious surface expression north of the Qilian Shan fold‐and‐thrust belt, but may link eastward with multiple faults in the northern Hexi Corridor and southern Alxa block. To better understand the potential connectivity and displacement transfer between the ATF and the northern Hexi Corridor fault array, we carried out a multidisciplinary field and remote sensing‐based investigation of the actively deforming Heishan and Jinta'Nanshan region north of Jiayuguan City. We document Quaternary sinistral strike‐slip motion on the Heishan fault (HF) system and active sinistral transpression within a 70‐km‐long, E‐W deforming belt east of the Heishan, which is characterized by multiple left‐stepping, en‐échelon Quaternary folds and linking faults. Cosmogenic 10Be dating of displaced terrace surfaces yields a vertical slip rate of ∼0.2 mm/a for the northern Heishan thrust and a sinistral strike‐slip rate of 0.6 ± 0.2 mm/a for the HF. Within the uplifted core of the Heishan massif, the HF contains ductilely deformed Paleozoic basement lithologies with dextral‐sense shear fabrics that indicate that the modern HF has reactivated and inverted an older shear zone. A previously published magnetotelluric profile across the HF system suggests that it roots into a steep, deeply penetrating fault that is unlinked to the Qilian Shan thrust wedge. Instead, we suggest that the active sinistral deformation belt of the Heishan‐Jinta'Nanshan represents the eastward‐evolving, upper crustal expression of the modern ATF system.

“…In other words, factors A and S are the key factors that should be considered in the evolution model, which is also in accordance with the soil erosion model of the Revised Universal Soil Loss Equation (RUSLE) in the loess area. In addition, the coefficients and exponents in the model are difficult to measure directly 53,54 . To avoid this difficulty, we integrated the intelligence method to simulate the landform evolution process with the key factors of A and S.…”

The history of changes in the Earth’s surface can be investigated by numerical modelling of landform evolution. However, such models rely on evidence which is often removed through erosion or other surface processes. Here, we use archaeological observations from the remains of Wucheng City in Shanxi, China, which was built on a loess area during the Neolithic period, to reconstruct the paleo-surface of the area and inform a landform evolution model. We identify differences between the present-day and paleo-land surface which suggest the topography was previously much less rugged. We find that period of heightened erosion rate in the early Holocene coincides with the period of increased rainfall, suggesting climate was the primary control on landform evolution during this time. We conclude that paleo-surface observations taken from archaeological sites, as demonstrated by this study, are valuable tools to inform landform evolution models in other regions where evidence is limited.

Introduction: The academic community has demonstrated the link of athletic performance in track and field with critical factors of sports training, including the psychology of competition. Recently, research has been verified that athletic performance is also related to altitude, weather, ambiance, and the timing of the competition. There are no studies to provide theoretical and practical training experience in the regional environment of Ganzhou. Objective: This paper analyzes the influence of altitude training in professional performance athletes. Concurrently, analysis of the physiological and biochemical indicators of the athletes is performed. Methods: Several long-distance runners had an 8-week altitude training. Analyzed the physiological and biochemical indicators of the athletes before and after the training. At the same time, perform mathematical-statistical analysis on the performance of long-distance runners before and after training. Results: After altitude training, hemoglobin and red blood cells showed a significant decrease (P<0.01). After training, athletes’ performance improved considerably (P<0.01). Conclusion: Training at different altitudes may promote an ascending curve in the athletes’ performance until a plateau in the fourth week of training.
