Evolution of the Dead Sea brine during the last glacial cycle from chemical compositions of interstitial soluble salts in sedimentary sections

This data set provides temporal variations in the Na/Cl, Mg/Cl, Br/Cl, and Br/Mg ratios of the deep (hypolimnion) and the overlying (epilimnion) brines of Lake Lisan that filled the Dead Sea Basin between ~100-13 ka period were retrieved from soluble salts within the lake's sediments. The soluble salts were extracted from cores drilled in the Dead Sea deep and shallow DSDDP cores numbers 5017-1-A and 5017-3-C, respectively, and from the Marginal outcrops of the Lisan Fm. exposed in the Perazim Valley (section PZ-1) and the White Hill (section GL-1). The ages from cores 5017-1-A and the marginal exposure of the White Hill section GL-1 were calculated using the relevant Time-Depth models. All the data are presented in Suppl. Table 1 to Suppl. Table 6. Suppl. Table 2 contains data from Levy et al., 2017.

本数据集提供了约100~13 ka期间充填死海盆地的利桑湖（Lake Lisan）深层卤水（湖下层（hypolimnion））与上覆卤水（湖上层（epilimnion））的Na/Cl、Mg/Cl、Br/Cl及Br/Mg比值的时间变化特征。该数据提取自湖泊沉积物中的可溶性盐类，这些盐类分别取自死海深海与浅海的死海钻探计划（Dead Sea Drilling Project, DSDDP）岩芯5017-1-A号和5017-3-C号，以及佩拉济姆谷（PZ-1剖面）与白龙山（GL-1剖面）出露的利桑组（Lisan Fm.）边缘露头。岩芯5017-1-A与白龙山GL-1剖面边缘露头的年代，均通过相应的时间-深度模型计算得到。所有数据均见于补充表1至补充表6，其中补充表2收录了Levy等人2017年的研究数据。
