The Golo River drains a steep catchment (average gradient of 30 m km⁻¹, surface of 1214 km²) in the northeast part of Corsica Island, delivering sediments to the Ligurian Sea. In this study, we review and revise the geologic map and constrain the extent of the Golo coastal alluvial plain formations and their relative and absolute chronology. To update the surface extent of each formation, we performed a geomorphologic analysis with DEMs and satellite imagery data coupled with an extensive pedogenic and sedimentary field observations database, including a new borehole of 117,4 m depth. Additionally, we performed in-situ cosmogenic ¹⁰Be analysis from a depth-profile in the well-preserved alluvial terrace Fy2, yielding a minimum age of 70 ka for its emplacement. Our new chronology, based on cosmogenic ¹⁰Be and soil chronosequences, implies older ages than those previously obtained with luminescence methods. Soil mixing by bioturbation is proposed as a possibility to explain differences between luminescence and ¹⁰Be ages. In this scenario, ¹⁰Be dates the original deposition of the alluvial terrace, while luminescence dates a later soil development. We highlighted at least five outcropping alluvial terraces in the Golo coastal plain, which are controlled by sea-level fluctuations and were most likely deposited during past sea-level highstands (close to present-day sea-level). Moreover, we identified from a borehole more than 117 m of coarse fluvial sediments in the plain, that do not outcrop at the surface. New cosmogenic ²⁶Al/¹⁰Be burial ages suggest that this sedimentary unit results from a thick accumulation of fluvial material filling a zone significantly affected by subsidence, probably accommodated by a normal fault during the Early Quaternary.

高洛河在科西嘉岛的东北部排泄了一个陡峭的集水区（平均坡度为30 m km ^-1，表面为1214 km ²），将沉积物输送到利古里亚海。在这项研究中，我们审查并修订了地质图，并限制了Golo沿海冲积平原地层的范围及其相对和绝对年代。为了更新每个地层的地表范围，我们使用DEM和卫星图像数据进行了地貌分析，并结合了广泛的成岩作用和沉积野外观测数据库，包括一个新的117,4 m深度的井眼。此外，我们进行了原位宇宙成因¹⁰从保存完好的冲积阶地Fy2的深度剖面进行分析，其放置的最小年龄为70 ka。我们基于宇宙成因的¹⁰ Be和土壤时间序列的新年表，比以前用发光方法获得的年龄要大。有人提出通过生物扰动混合土壤来解释发光和¹⁰ Be年龄之间的差异。在这种情况下，¹⁰可以追溯到冲积阶地的原始沉积，而发光则追溯到后来的土壤发育。我们强调了在Golo沿海平原上至少有五个露头冲积阶地，这些冲积阶地受海平面波动的控制，最有可能在过去的海平面高位（接近今天的海平面）沉积。此外，我们从一个钻孔中发现了平原上不超过11​​7 m的粗糙河流沉积物，这些沉积物没有在地表露头。新的具有成因作用的²⁶ Al / ¹⁰ Be埋葬年龄表明，这种沉积单元是由河流物质的大量堆积所造成的，该物质充满了受沉降影响很大的区域，很可能是第四纪早期的正常断层所容纳的。
