The Quaternary filling of the Upper Rhine Graben is an excellent archive to reconstruct sediment dynamics in response to climate change, in particular related to past glaciations of the Swiss Alpine Foreland. Here, a sediment sequence recovered by drilling for exploration purposes near Kronau is investigated, using a combination of sedimentological logging, provenance studies (heavy minerals and clast petrography), and luminescence dating. Several phases of coarse sediment aggradation are identified that possibly correlate to Marine Isotope Stages (MIS) 12 (478–424 ka), 10 (374–337 ka), 8 (300–243 ka), 6 (191–130 ka) and/or 4 (71–57 ka), and 2 (29–14 ka). Several of these phases have previously also been reported from cores recovered in the major Quaternary depo-centre near Heidelberg. This suggests that the observed coarse aggradation in the Upper Rhine Graben can be assigned to various glaciations in northern Switzerland: Möhlin (MIS 12), Habsburg (MIS 10 or 8), Beringen (MIS 6), an unnamed glacial advance during MIS 4, and Birrfeld (MIS 2). However, due to the limited data available, this hypothesis and the suggested correlations require further confirmation by applying the approach presented here to further cores from the Upper Rhine Graben.

探索上莱茵河格拉本的第四纪沉积与瑞士北部的冰期历史之间的可能联系

上莱茵河格拉本的第四纪充填物是一个很好的档案库,可以重建响应气候变化的沉积物动力学,特别是与瑞士高山前陆的过去冰川有关。在这里,结合了沉积学测井,物源研究(重矿物和岩相岩石学)以及发光测年的组合,研究了为钻探而在克罗瑙附近通过钻探回收的沉积物序列。确定了几个阶段的粗沙沉积物聚集,这可能与海洋同位素阶段(MIS)12(478-424 ka),10(374-337 ka),8(300-243 ka),6(191-130 ka)和/或4(71–57 ka)和2(29–14 ka)。这些阶段中的几个阶段以前也曾从海德堡附近的主要第四纪沉积中心回收的岩心中报道过。这表明,在莱茵河上格拉本地区观测到的粗暴沉积可以归因于瑞士北部的各种冰川:穆林(MIS 12),哈布斯堡(MIS 10或8),白令根(MIS 6),这是MIS 4期间未命名的冰川运动。和比尔费尔德(MIS 2)。但是,由于可用的数据有限,因此需要通过将此处介绍的方法应用于上莱茵格拉本的其他岩心来进一步证实这一假设和建议的相关性。
