Dating of glacial advances is an important contribution for the reconstruction of Mediterranean-scale mountain climate during cold spells of the Late Pleistocene. Such reconstructions allow tracking of moisture transport from the central Mediterranean basin towards the north and east. In southeastern Europe, the main target region of this pilot study, almost no chronology of moraine deposits exist so far. The moraine deposits in the target regions are lacking both local and regional correlation. Thus, a robust stratigraphic framework for moraine deposits by means of dating cosmogenic Be is required. During a pilot field study in a cross section of the central South Carpathians, local moraine successions have been sampled which indicate a stronger moisture advection from the south during the Last Glacial Maximum, as compared to the early Holocene. A similar pilot study is recommended by review of project KU 1298/13 and envisaged in the Rila massiv of Bulgaria. Purified quartz samples from the South Carpathians are ready for target preparation, similar to late Wuermian samples from Corsica (project KU1298/7-3), for which funding external measurements is lacking and requested herewith.

冰川前进的年代测定是重建晚更新世寒冷期的中世纪尺度山地气候的重要贡献。这样的重建可以跟踪从地中海中部盆地向北部和东部的水分输送。在欧洲东南部（这项试点研究的主要目标地区），迄今为止几乎没有冰碛沉积物的年代学。研究区的冰碛沉积缺乏局部和区域的对比。因此，需要一个强大的冰碛沉积物的地层框架，通过测年宇宙成因Be。在南喀尔巴阡山脉中部的一个横截面的试点实地研究中，当地的冰碛序列已被采样，这表明一个较强的水分平流从南部在末次冰期最大，全新世早期相比。对KU 1298/13项目的审查建议进行一项类似的试点研究，保加利亚的RilaZagov也设想进行这项研究。来自南喀尔巴阡山脉的纯化石英样品已准备好用于目标制备，类似于来自科西嘉的乌尔阶晚期样品（项目KU 1298/7-3），缺乏外部测量的资金，特此请求。
