Quantification and geochemical characterization of total mass fluxes in river catchments of the Rhenish Massif and the Black Forest, Germany

我们的目标是确定长期的侵蚀速率以及最近的质量通量，包括其地球化学和稳定同位素的签名，在四个选定的集水区的莱茵高原和黑森林（德国）。空间平均侵蚀率整合在全新世/晚更新世将来自10 Be浓度的石英在河流沉积物中从不同的子流域的每个集水区。将根据径流数据和溶解和悬浮河流负荷的地球化学（主要和微量元素）特征确定这些集水区最近的质量通量。将使用水和溶解负荷（H、C、O、S）的稳定同位素特征，对有机物、大气和人为输入进行校正。地球化学调查将辅之以地貌分析，以确定地貌参数，如每个取样子盆地的地形和坡度分布。我们的调查将产生不同的时间尺度（几年和~104年）的侵蚀率，并将提供定量限制晚第四纪剥蚀的典型的中欧山脉。

We aim to determine long-term erosion rates as well as recent mass fluxes including their geochemical and stable isotope signatures in four selected catchments of the Rhenish Massif and the Black Forest (Germany). Spatially-averaged erosion rates integrated over the Holocene/Late Pleistocene will be derived from the 10Be concentration of quartz in river sediments from the different subbasins of each catchment. Recent mass fluxes out of these catchments will be determined from run-off data and the geochemical (main and trace elements) signatures of dissolved and suspended river loads. These will be corrected for organic, atmospheric, and anthropogenic inputs using the stable isotopic signatures of water and dissolved loads (H, C, O, S). The geochemical investigations will be complemented by a geomorphologic analysis to define geomorphic parameters such as relief and slope distribution for each of the sampled subbasins. Our investigations will yield erosion rates on different timescales (a few years and ~104 years) and will provide quantitative constraints on the Late Quaternary denudation of mountain ranges typical of central Europe.
