Late Quaternary glaciations, periglacial and aeolian geomorphic processes as contribution to the paleoclimatic evolution of continual mountains in Western Mongolia (Altay and Khangay)

调查的主要目的是蒙古西部山脉晚更新世和全新世冰川和风成覆盖沉积的范围和原因。研究区域集中在中亚沙漠和草原景观与西伯利亚森林地区之间的重要地点。研究的重点是：（1）晚第四纪最大冰期的时间。(2)风成沉积和古土壤的时期。(3)西风带的区域气候环流和季风对（古）冰川和黄土沉积的可能影响。为了回答这一研究问题，冰川地貌和沉积物和风成覆盖沉积物将被映射，采样，分析与沉积学和土壤学的方法，并与放射性碳和发光定年。一个特别的重点将放在不同档案的冰缘修改。调查从蒙古最西部的现代冰川阿尔泰山开始，一直到蒙古中部的汉盖山，涉及海拔、平衡海拔和湿度的区域差异。本研究的结果将与中亚其他地区的研究结果进行对比，以突出区域古气候演化的异同。

Main aim of the investigation is the extent and causes of late Pleistocene and Holocene glaciations and aeolian cover sediments in the mountain ranges of western Mongolia. The study area concentrates on important sites in the area between the deserts and steppe landscapes of Central Asia and the forest areas of Siberia. Following research question should be investigated: (1) Timing of maximum late Quaternary glaciations. (2) Periods of aeolian sedimentation and paleosols. (3) Regional climatic circulation of the Westerlies and possible monsoonal influences on the (paleo) glaciations and on the sedimentation of loess. To answer this research questions glacial landforms and sediments and aeolian cover sediments will be mapped, sampled, analyzed with sedimentological and pedological methods and dated with radiocarbon and luminescence. A special focus will be placed on the periglacial modification of the different archives. The investigation starts in the modern glaciated Mongolian Altai in the westernmost part of Mongolia towards the Khangay Mountains in the central part of Mongolia regarding the regional differences in elevation, equilibrium altitude elevation and moisture. The results of this study will be correlated with those of other areas of Central Asia to highlight similarities and differences in the regional paleoclimatic evolution.
