摘要
在法国北部阿尔卑斯cha ne des hurti丘陵植被带的Les Ételles(700米)，对一个新的沉积序列进行了详细的花粉分析。植被的冰河历史得到了10个AMS定年的支持。将主要花粉分类群的相对丰度变化与瑞士湖泊沉积物中ð 18O的变化以及GRIP冰芯记录进行了比较。它们突出了植被如何对轻微的气候波动作出反应。证实了该地区栎科、桤木科和榛科的冰川分布，从而对邻近地区的一些冰川沉积序列(下- dauphin)进行了新的解释。
Le tardiglaciaire des Ételles (Alpes françaises du Nord) : instabilité climatique et dynamique de végétation
A detailed pollen analysis has been conducted in a new sedimentary sequence taken at Les Ételles (700 m), in the hill vegetation belt in the Chaîne des Hurtières (Northern French Alps). The Lateglacial history of the vegetation has been supported by 10 AMS datings. Variations in relative abundance of main pollen taxa were compared with variations in ð18O in Swiss lacustrine sediments and with the GRIP ice-core record. Those highlight how the vegetation reacted to minor climatic oscillations. The Lateglacial spread of Quercus, Alnus and Corylus in the region is confirmed, thus allowing a new interpretation of some Lateglacial sedimentary sequences at an adjacent region (Bas-Dauphiné).
