Lithological and seasonal influences on Li isotope fractionation during silicate weathering
Description
Data Repository Items for our upcoming manuscript on "Lithological and seasonal influences on Li isotope fractionation during silicate weathering" submitted to Geochimica et Cosmochimica Acta. 2 files are attached in this repository: Manuscript Tables: Table 1, Table 2, Table 3 and Table 4 and Table S1 located in the manuscript and supplementary material are included in separate sheets. Supplementary Data File 1: The supplementary data file contains the complete dataset for all individual samples and elements measured in this study. Table captions: Table 1. Information on sampling localities Table 2. Selected in-situ geochemical data, dissolved load elemental concentrations and Li isotopic ratios from all localities. Full elemental data are in supplementary file 1. a Mean value from all repeated samples from each season is presented. b “W” indicates mean value from wet summer season samples. “D” indicates mean value from dry winter season values. c “n” indicates how many repeated samples obtained to calculate mean values d “ND” indicates this variable was not determined during analyses. Table 3. Li concentrations and isotopic values from bedload and bedrock from all localities. The lithology of the bedrock digested is also listed. a “ND” indicates this variable was not determined during analyses. Table 4. Breakdown of bedload clay mineralogical abundances. Table S1: Certified reference materials (CRM) and their errors for lithium isotopic measurements. Run 1 includes only wet season samples from July-August 2019. Run 2 includes both dry and wet season samples from January 2020 and September 2021 respectively. “n” indicates how many repeated measurements for each CRM during the run.
