Eifel层状沉积物档案（ELSA）由来自maar湖泊的几个岩心组成，其中包括过去14万年的许多tephra层。沉积物岩心通过14C和热释光测定年代，并调整到格陵兰岛的冰期-间期序列。在最后一次冰期旋回中，艾菲尔火山田是几个广泛分布的tephra层的来源，即Laacher See， Eltville， Rambach和Rocourt tephra。然而，到目前为止，只确定了Laacher See Tephra的相应源火山。在这项研究中，我们使用玻璃和斜辉石地球化学将剩余的温层与东、西艾菲尔火山场可能的喷发中心联系起来。虽然我们证明Eltville Tephras起源于较早的Laacher See火山喷发，在东艾菲尔火山场内以24300 a bp的速度喷发，但Rambach和Rocourt Tephras来自西艾菲尔火山场，分别以27900 a bp和75000 a bp的速度喷发自Wartgesberg和pululmaar。火山活动的高峰期分别是1万~ 3万bp和6万~ 8万bp，因此火山喷发的时间大约是末次冰期旋回的最低温度。在最后一次间冰期，各个喷口之间最长的休眠期长达约3万年。
The Eifel Laminated Sediment Archive (ELSA), which comprises several cores from maar lakes, includes numerous tephra layers spanning the last 140 000 years. The sediment cores are dated by 14C and thermoluminescence as well as tuned to Greenland stadial–interstadial successions. Within the last glacial cycle, the Eifel Volcanic Fields are source to several widespread tephra layers, namely the Laacher See, Eltville, Rambach and Rocourt Tephra. However, a corresponding source volcano was so far only identified for the Laacher See Tephra. In this study we use glass and clinopyroxene geochemistry to link the remaining tephra layers to possible eruption centers within the West and East Eifel Volcanic Fields: while we demonstrate that the Eltville Tephra originated from an earlier eruption of the Laacher See Volcano at 24 300 a bp from within the East Eifel Volcanic Field, the Rambach and Rocourt Tephras are sourced from the West Eifel Volcanic Field and erupted from Wartgesberg at 27 900 a bp and Pulvermaar at 75 000 a bp, respectively. Phases of volcanic activity peaked at 10 000–30 000 and 60 000–80 000 a bp and were thus erupted around the temperature minima of the last glacial cycle. The longest phase of dormancy between individual vents was around 30 000 years long, within the last interglacial.
