15 long sediment cores from Eifel dry maar lakes have been drilled between 2001 and 2004 by the ELSA project. Colour logging provides the basis for an ice-core-tuned stratigraphy, and 14C dates give absolute dates for interstadials. All 15 cores show repeatedly the same lithological features which will be synthesized into a general succession of lithological units (Normalprofil). Combination of lithology and stratigraphy for all 15 cores will give a complete record of all major climatic, environmental and volcanic events in the Eifel during the last glaciation. Geochemical, sedimentological and mineralogical analysis will be used to understand the environmental and climate causes for the event layers. Time series analysis on the succession of event layers and on the logging data will be use to detect those periodicities and related processes that controlled sedimentation patterns in the Eifel region during MIS2-5.

Elsa项目在2001年至2004年之间钻了15个来自Eifel Dry Maar Lakes的长沉积物核心。颜色日志记录为冰核调节的地层提供了基础，14C日期为星际内部提供了绝对日期。所有15个核心反复呈现出相同的岩性特征，这些特征将被合成为岩性单元（正常生产）的一般继承。在最后一次冰川期间，所有15个核心的岩性和地层的结合将为EIFEL中的所有主要气候，环境和火山事件提供完整的记录。地球化学，沉积和矿物学分析将用于了解事件层的环境和气候原因。关于事件层和记录数据连续的时间序列分析将用于检测MIS2-5期间EIFEL区域中控制沉积模式的那些周期和相关过程。
