The climate in central Europe during the last 60 ka is characterized by rapid temperature and moisture changes and strong cold periods (Heinrich events). All these variations are preserved in sediments of marine and also some terrestrial archives. Here we present a continuous, terrestrial sediment record with almost all Greenland stadials and Heinrich events between 60 and 13 ka visible from carbonate roundness of the Eifel Laminated Sediment Archive Dust Stack-20 and CaCO3 data for central Europe. The carbonate roundness data show almost all stadials between 60 and 13 ka. CaCO3 data show a general transport system change with the beginning of Heinrich event 3. Since there are no carbonates west of the Auel Maar, we conclude that the eolian-transported grains were not transported by westerly but easterly winds. These postulated easterly winds during the last glacial maximum are supported by similar findings of previous works.

60 至 13 ka 中欧 Auel 干玛尔的风成沉积

过去 60 ka 中欧气候的特点是温度和水分快速变化以及强烈的寒冷期(海因里希事件)。所有这些变化都保存在海洋沉积物和一些陆地档案中。在这里,我们展示了一个连续的陆地沉积物记录,从 Eifel Laminated Sediment Archive Dust Stack-20 和 CaCO 的碳酸盐圆度中可以看到几乎所有格陵兰 stadials 和 60 到 13 ka 之间的 Heinrich 事件3中欧数据。碳酸盐圆度数据显示了 60 到 13 ka 之间的几乎所有视距。碳酸钙3数据显示,随着海因里希事件 3 的开始,一般的运输系统发生了变化。由于 Auel Maar 以西没有碳酸盐,我们得出结论,风成运输的谷物不是由西风而是东风运输的。这些在最后一次冰河最大值期间假定的东风得到了先前工作的类似发现的支持。
