Geochemical, modelled, and compiled (literature-based) data used to constrain the role of marine authigenic clay formation in setting the lithium isotope composition of seawater

Description: This data publication is supplementary to a study on the effect of the formation of cation-rich authigenic aluminosilicate clays during the early diagenesis of detrital sediments on the seawater lithium isotope composition by Läuchli et al., (2025). The dataset contains elemental ratios and lithium isotope ratios from (1) river sediments sampled in March 2019 the vicinity of the coastline, (2) marine surface sediments from Multlicorer sampling device from the R/V Sonne Cruise SO156 and the R/V Sonne Cruise SO102 and (3) marine samples from the gravity core sites GeoB 7139-2 (R/V Sonne Cruise SO156), GeoB 3304-5 (R/V Sonne Cruise SO102) and 22SL (Sonne Cruise SO161-5). The dataset is provided here as a single .xlsx file containing one data sheet. Metadata including International Generic Sample Numbers (IGSNs) are provided for each sample. The data were acquired as part of the German Science Foundation (DFG) priority program SPP-1803 “EarthShape: Earth Surface Shaping by Biota” initiated and lead by Friedhelm von Blanckenburg and Todd Ehlers. The GeoB cores samples were provided by the MARUM Research Center (Bremen). The 22SL Gravity Core was stored and supplied by the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR, Hannover).
