Stratigraphy and lithology of 15 laminated late Pleistocene sediment cores from Eifel dry maar lakes

ELSA项目在2001年至2004年期间从艾菲尔干沼泽湖钻探了15个长沉积物岩心。彩色测井为调整冰芯的地层学提供了基础，而14C的年代则给出了间冰期的绝对年代。所有15个岩心都反复显示相同的岩性特征，这些特征将被合成为岩性单元的一般演替（normal剖面）。所有15个岩心的岩性和地层学组合将给出最后一次冰期期间艾菲尔山脉所有主要气候、环境和火山事件的完整记录。地球化学、沉积学和矿物学分析将用于了解事件层的环境和气候原因。通过对事件层序列和测井资料的时间序列分析，将发现MIS2-5期间控制Eifel地区沉积模式的周期性和相关过程。

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.
