Abstract

We propose a new relative shore-level curve for the Aarhus Bugt area, an embayment in eastern Jylland, Denmark, based on a compilation of published and new radiocarbon ages of organic material. Lakes existed in the area during the Late Glacial and Early Holocene. Lake level rose gradually until the region was inundated by the sea at c. 9000 cal. years BP. The relative sea level reached a high stand at about 6000 cal. years BP, when the local relative sea level was c. 3 m above present-day mean sea level. The Aarhus Bugt area was inundated by the sea later than the Limfjord area in northern Jylland, but earlier than the Lillebælt region in southern Denmark. The shore-level curves for these areas differ partly because the glacio-isostatic uplift was more pronounced in the Limfjord area than farther south and partly because the northern regions were inundated by the sea earlier than the southern areas.
丹麦奥胡斯堡地区晚冰期和全新世海岸水平变化
根据已发表的和新的有机材料放射性碳年龄汇编,我们提出了丹麦Jylland东部海湾Aarhus Bugt地区的新的相对海岸线。该地区在冰川晚期和全新世早期就存在湖泊。湖面逐渐上升,直到公元前三世纪该地区被海水淹没。9000卡年BP。当当地的相对海平面为c。高于当前平均海平面3米。奥胡斯-Bugt地区被海水淹没的时间晚于Jylland北部的Limfjord地区,但早于丹麦南部的Lillebælt地区。这些地区的海岸线不同,部分原因是冰川均衡隆起在Limfjord地区比更南的地区更明显,部分原因在于北部地区比南部地区更早被海水淹没。
