Coastal change during the Mid‐ to Late Holocene at Luce Bay, South West Scotland, is examined using morphological, stratigraphic and biostratigraphical techniques supported by radiocarbon dating. Deglaciation left extensive sediments, providing a source for depositional coastal landforms. Glacio‐isostatic uplift resulted in the registration of evidence for former relative sea levels (RSLs), which support the pattern of Holocene RSL change for the northern Irish Sea as determined by shoreline‐based Gaussian trend surface models. The rate of RSL rise was rapid from before ca. 8600 to ca. 7800 cal a BP, but then slowed, changing by <3m over the next 3000 years, a pattern reflected in the convergence of shorelines predicted in the models. By ca. 4400 cal a BP RSL was falling towards present levels. As these changes were taking place, coastal barriers developed and dunes formed across them. In the West of the Bay, a lagoon forming to landward of the barriers and dunes acted as a sediment sink for dune sand. Changes in the coastal landscape influenced the occupation of the area by early human societies. This study illustrates the value of combining an understanding of process geomorphology, RSL and archaeology in studies of coastal change. © 2020 The Authors.

苏格兰西南部卢斯湾的全新世海岸变化

使用放射性碳测年支持的形态学、地层学和生物地层学技术检查了苏格兰西南部卢斯湾全新世中晚期的海岸变化。冰川消融留下了广泛的沉积物，为沉积沿海地貌提供了来源。冰川等静压抬升导致记录了前相对海平面 (RSL) 的证据，这支持了由基于海岸线的高斯趋势表面模型确定的爱尔兰北部全新世 RSL 变化的模式。RSL 的上升速度比之前更快。8600 到大约 7800 cal a BP，但随后放缓，在接下来的 3000 年中变化小于 3m，这一模式反映在模型中预测的海岸线会聚中。通过约。4400 cal a BP RSL 正在下降到目前的水平。随着这些变化的发生，海岸屏障发达，沙丘形成。在海湾的西部，一个泻湖形成到障碍物和沙丘的陆地上，作为沙丘的沉积物汇。沿海景观的变化影响了早期人类社会对该地区的占领。这项研究说明了结合对过程地貌学、RSL 和考古学的理解在海岸变化研究中的价值。© 2020 作者。John Wiley & Sons, Ltd. 出版的第四纪科学杂志 海岸变化研究中的 RSL 和考古学。© 2020 作者。John Wiley & Sons, Ltd. 出版的第四纪科学杂志 海岸变化研究中的 RSL 和考古学。© 2020 作者。John Wiley & Sons, Ltd. 出版的第四纪科学杂志
