¹⁰Be age datings of Late Würmian erratics from Vorarlberg (Austria) and southern Germany

This study presents a ¹⁰Be dataset from Vorarlberg (Austria) and the adjacent Alpine foreland of southern Germany. Out of a total of forty-three samples collected in the field, twenty-five samples of quartz-bearing erratic boulders of Late Würmian age were selected for analyses, measurements and calculations after careful pre-analysis assessment of the sample quality and the potential stratigraphic value. The samples were taken from five localities in Vorarlberg and one locality in southern Germany. The output of fifteen samples passes the threshold in a statistical accuracy assessment. These samples are used in the final determination of the minimum exposure ages. Subsequently, the datings were assessed versus the existing regional morpho- and chronostratigraphic framework, which was erected based on geomorphological and sedimentological data in combination with ¹⁴C age datings. The ¹⁰Be ages at three localities fit in with the stratigraphic framework, while three are considered slightly young or too young when compared with the existing chronologies. The results are considered promising and justify further ¹⁰Be analysis to improve the deglaciation chronology of the area and to find potential calibration sites for cosmogenic surface exposure dating.
