Würmian paleoclimate and glaciation in Corsica

通过对科西嘉岛冰川沉积和三聚氰胺的系统研究，绘制出了(晚)乌尔眠时期冰川的最大范围图。古代平衡线高度(ELA)模式的重建提供了有关地中海西北部维尔米亚最大冰期期间区域气候的重要信息。然而，需要建立一个强有力的冰河沉积地层框架。为了确定维尔米期冰雹沉积的年龄限制，我们的目标是通过测定10Be宇宙成因的同位素，来确定上升于符尔棉期冰雹之上的巨石的暴露年龄。中尺度地形似乎控制着科西嘉岛的ELA模式，而这种控制的细节，如漏斗效应的量化，可能适用于许多山脉。

Systematic investigation of glacial deposits and trimelines in Corsica enabled to map the maximum extent of glaciers during the (late) Würmian. The reconstruction of the ancient equilibrium line altitude (ELA) pattern provides important information on the regional climate during the Würmian maximum glaciation in the nordwestern Mediterranean realm. However, a robust stratigraphic framework for moraine deposits needs to be established. To establish age constraints for the deposition of moraines within the Würmian we aim to determine exposure ages of large boulders rising above Würmian moraines by dating 10Be cosmogenic isotopes. Mesoscale topography appears to control ELA pattern on Corsica, and paricularities of this control such as quantification of funneling effects are potentially applicable in many mountain ranges.
