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

2001年至2004年，ELSA项目从艾菲尔干玛尔湖钻探了15个长沉积岩芯。彩色测井为冰芯调谐地层学提供了基础，14C测年提供了陆间地层的绝对日期。所有15个岩心重复显示相同的岩性特征，这些岩性特征将被合成成一个一般的岩性单位序列(正常剖面)。所有15个岩芯的岩性和地层学组合将完整地记录最后一次冰川期间艾菲尔的所有主要气候、环境和火山事件。将使用地球化学、沉积学和矿物学分析来了解事件层的环境和气候原因。对事件层序列和测井数据的时间序列分析将被用来检测在MIS2-5期间控制Eifel地区沉积模式的周期和相关过程。

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.
