Abstract:

This dataset consists of 17 profiles sampled in 2010, 2013, and 2018. Sampling was conducted on river banks of the Loire River and some tributaries to enrich the dataset (Maniere et al. 2025) when any suitable coring site was identified. These profiles were used to define a global geochemical signature from these sub-basins. Analyses focused on major and trace elements compositions (heavy metals and metalloids), all conducted using the same analytical procedures at the French National Centre for Scientific Research (CNRS) SARM-CRPG facilities (Nancy, France; https://sarm.cnrs.fr). In addition, total and organic carbon were carried out at the GéHCO research unit (University of Tours) and grain-size at the LSCSE research unit (CEA-CNRS-UNSQ).
