Geomorphological processes and the change of climatic conditions during the Quaternary control the landscape evolution in the internal drainage areas of western Mongolia. Especially the interplay of fluvial, lacustrine and aeolian processes create different landforms, such as alluvial fans, beach bars and dune fields. Their associated sediment archives and sediment transport pathways reflecting the late Quaternary landscape evolution. The project will analyze the geomorphological processes and sediment archives and will constrain the timing of different landforms and deposits by using TCN and OSL dating techniques. The synthesis of results should provide comprehensive landscape model of sedimentary processes under variable climates in this region with extreme continental climatic conditions, and provide analogs for other similar regions.

第四纪地貌过程和气候条件的变化控制着蒙古西部内流域的景观演化。特别是河流、湖泊和风成过程的相互作用创造了不同的地貌，如冲积扇、海滩坝和沙丘地。它们相关的沉积物档案和沉积物运输路径反映了第四纪晚期的景观演化。该项目将分析地貌过程和沉积物档案，并利用 TCN 和 OSL 测年技术来限制不同地貌和沉积物的形成时间。结果的综合应提供该地区极端大陆气候条件下多变气候下沉积过程的综合景观模型，并为其他类似地区提供类比。
