Sulphur isotope geochemistry of black shale-hosted antimony mineralization, Arnsberg, northern Rhenish Massif, Germany: Implications for late-stage fluid flow during the Variscan orogeny
|
Abstract: Vein-type and bedding-concordant mesothermal (180-410[degrees]C) stibnite-sulphosalt mineralization at Arnsberg, NE Rhenish Massif, Germany, is hosted by Carboniferous pyrite-rich black shales and siliceous limestones. A detailed sulphur isotope study of the stibnite-sulphosalt mineralization and pyrite from a variety of regional host-rock lithologies has been carried out using an in situ laser combustion technique. The [delta]^sup 34^S values of stibnite of various textural types are distinctly negative and lie in a narrow range between -23.9[per thousand] and -17.1[per thousand] ...
