Abstract In the eastern Qilian Shan, a flight of fluvial terraces developed along Jinta River valley are deformed across Nanying anticline. Four individual preserved at different elevations above river, and higher terrace treads draped by systematically thicker aeolian loess. Optically stimulated luminescence dating deposits base loess provides constraints on timing surface abandonment; were abandoned 69 ± 4 ka B.P. (T4), 57 (T3), between 34 3 (T2), respectively. Differential GPS measurement...
Abstract Background Research interest in plant essential oils has increased significantly due to their natural properties and consumer demand for safer methods of food preservation. Plants produce large amounts secondary metabolites, which have potential activity against fungal pathogens. This study aimed at screening antifungal effects on citrus Penicillium digitatum , morphological effect finally determine are the most effective. Results The EC 50 seven selected cinnamon (0.424 μL/mL),...
Abstract The actively deformed foreland of eastern Qilian Shan (mountains) contains well‐preserved geomorphic features such as erosion surfaces, river terraces and tectonically uplifted alluvial fans, providing suitable archives for research on regional tectonic activities palaeoclimatic changes. These surfaces are well dated by using a combination magnetostratigraphy, electron spin resonance, thermoluminescence, infra‐red stimulated luminescence, radiocarbon dating, correlation with the...
Abstract The Weihe River in central China is the largest tributary of Yellow and contains a well-developed strath terrace system. A new chronology for past 1.11 Ma spectacular flight terraces along upper near Longxi defined based on field investigations loess—paleosol sequences magnetostratigraphy. All are strikingly similar, having several meters paleosols that have developed directly top fluvial deposits located treads. This suggests abandonment each by river incision occurred during...
The drainage density ( D d ) is an important index to show fluvial geomorphology. study on helpful understand the evolution of whole hydrological and geomorphic process. Based Shuttle Radar Topography Mission 90-m digital elevation model, network basins along eastern margin Qinghai–Tibet Plateau extracted using a terrain morphology-based method in ArcGIS 10.3, calculated. spatial characteristics are analyzed, relationship between its influencing factors, e.g., topography, precipitation,...
The grain size composition and distribution of river sediments are important for understanding regional geomorphological evolution, source-sink processes drainage ecology. Shiyang River basin, an inland system in northwestern China, provides environmental context within which to investigate the relationship between sediment particle factors. Based on analysis characteristics modern riverbed sediments, basin parameters lithology, it is found that median (Md) shows a decrease trend from...
