    • Molecular-scale speciation of germanium and copper within sphalerite from Central Tennessee mining district (TN), Red Dog mining district (AK), and Metaline mining district (WA)

    Metadata Updated: July 6, 2024

    Oxidation state and bonding environment of Ge and Cu in ZnS and Zn mineral concentrates from a variety of sources [Central Tennessee mining district (TN), Metaline mining district, (WA), and Red Dog mine (AK)] were determined by linear combination fits from x-ray absorption spectroscopy (XAS) analysis. Sphalerites from the East Tennessee mining district contained Ge in concentrations that were too low to generate a X-ray absorption spectra with an edge step. When applicable, Ge content in quartz was determined using XAS edge steps. Data and methods reported are part of a research study published here: Hayes SM, McAleer RJ, Piatak NM, White SJO, Seal RR II (2023), A novel nondestructive workflow for examining germanium and co-substituents in ZnS. Front. Earth Sci. 11:939700. doi: 10.3389/feart.2023.939700
