Repartitioning of co-precipitated Mo(VI) during Fe(II) and S(-II) driven ferrihydrite transformation: Datasets and Supplementary Materials
Federated Research Data Repository / dépôt fédéré de données de recherche
Schoepfer, Valerie A.; Lindsay, Matthew B.J. — 2022-05-03 This file contains aqueous and solid phase geochemical data resulting from a set of experiments documenting the repartitioning of initially co-precipitated molybdenum(VI) during electron transfer and atom exchange of ferrihydrite. Data include aqueous Fe, S, and Mo concentrations, as well as pH and Eh. Solid phase data consists of spectra from K- and LIII- edge X-ray absorption spectroscopy, X-ray diffraction patterns, and d-spacings associated with transmission electron microscopy-selected area electron diffraction. These data are associated with the article "Repartitioning of co-precipitated Mo(VI) during Fe(II) and S(-II) driven ferrihydrite transformation" by Schoepfer and Lindsay (In preparation).

Skierszkan, Elliott K; Carey, Sean K.; Fellwock, Matt; Jackson, Scott I; Fraser, Colin; Lindsay, Matthew B.J. — 2024-08-15 The data are associated with the article: "Seasonal controls on stream metal(loid) signatures in mountainous discontinuous permafrost" by Skierszkan,E.K.,Carey, S.K., Jackson, S.I., Fellwock, M., Fraser, C. & Lindsay, M.B.J. (2023). Seasonal controls on stream metal(loid) signatures in mountainous discontinuous permafrost, Science of The Total Environment, 908(167999). DOI: https://doi.org/10.1016/j.scitotenv.2023.167999. The data were used to investigate metal(loid) abundances and mobilization processes in water in a discontinuous permafrost region. The data consist of a compilation of analyses produced as part of baseline environmental monitoring at the proposed Coffee Gold Mine by its proponent, Newmont Corp, and supplemented with additional samples collected as part of a research project into geogenic metal(oid)s in permafrost regions led by Skierszkan et al.
