Antimony isotopic fractionation during dissolution of an Sb₂S₃–Sb⁰ assemblage and subsequent secondary mineral precipitation

This dataset contains all data underlying the figures and tables presented in the manuscript “Antimony isotopic fractionation during dissolution of an Sb₂S₃–Sb⁰ assemblage and subsequent secondary mineral precipitation” by Lali Carrière, Eléonore Resongles, Areej Adra, Pierre Le Pape, Rémi Freydier, Oleg S. Pokrovski, Sophie Ayrault and Corinne Casiot. It includes Supplementary Material) as well as EDX spectra, XANES spectra of reference compounds and experimental samples with associated linear combination fitting (LCF) results, and X-ray diffraction (XRD) data. In addition, the dataset provides data from the dissolution experiments in an Excel file (Tracking_dissolution_experiments) compiling the experimental conditions and the time-resolved monitoring of the system, including total dissolved Sb, Sb(III) and Sb(V) concentrations, δ¹²³Sb isotopic compositions, pH values, results of acid digestion of the initial solid material, and Sb release rates for all experiments. The file also includes the dataset used to construct Figure 7, including Sb mass distribution among dissolved and solid pools, saturation indices of secondary phases, and net reaction rates (Rnet).
