The aim of this project is to reconstruct the palaeoclimatological changes in the Dead Sea Basin and adjacent areas during the last two interglacials as archived in the ICDP Dead Sea Deep Drilling Project (DSDDP) sediment cores, using a unique combination of high-resolution sedimentological-mineralogical, geochemical and rock magnetic studies. A detailed comparison of the Holocene and Eemian sediment formations will be crucial for the understanding of interglacial climate variability in the central and eastern Mediterranean. Within this project we will also provide the first sedimentary record of the Younger Dryas and the MIS 5/6 transition in the Dead Sea Basin, these time intervals are preserved in none of the outcrops due to depositional hiatus. A second focus of the rock magnetic investigations will be on the genesis of the Fe-sulfide greigite, since greigite formation is strongly enhanced during wet climatic phases. A novel methodological approach for identifying flood and dust storm layers in Dead Sea sediments developed on existing core material from the western shore of the Dead Sea will also be applied, thus enhancing the Holocene time series of these event deposits.

该项目的目的是利用高分辨率沉积学的独特组合，重建死海盆地及邻近地区在最后两次间冰期期间的古气候变化，这些变化在 ICDP 死海深钻项目 (DSDDP) 沉积岩芯中存档。矿物学、地球化学和岩石磁性研究。全新世和峨眉纪沉积物形成的详细比较对于了解地中海中部和东部间冰期气候变化至关重要。在这个项目中，我们还将提供死海盆地新仙女木期和 MIS 5/6 过渡期的第一个沉积记录，由于沉积间断，这些时间间隔没有在任何露头中得到保留。岩石磁性研究的第二个重点将是硫化铁硅灰岩的成因，因为在潮湿的气候阶段，硅灰岩的形成强烈增强。还将应用一种新的方法来识别死海沉积物中的洪水和沙尘暴层，该方法是在死海西岸现有的岩心材料上开发的，从而增强了这些事件沉积物的全新世时间序列。
