Publikováno v: Geochimica et Cosmochimica Acta. 240:11-42

Understanding the physical basics of tectonic events, related fluid flow and ore deposition represents one of the great challenges in modern geosciences. In this contribution, Sm-Nd ages of hydrothermal fluorites and U-Pb ages of carbonates and iron

Reconstruction of a >200 Ma multi-stage 'five element' Bi-Co-Ni-Fe-As-S system in the Penninic Alps, Switzerland

Autor: Udo Neumann, Stefan Kreissl, Benjamin F. Walter, Thomas Wenzel, Gregor Markl, Axel Gerdes

Publikováno v: Ore Geology Reviews. 95:746-788

Hydrothermal five-element veins (Ag-Co-Ni-Bi-As) are mineral successions of native metals, encapsulated by Fe-Co-Ni arsenides and carbonates. Recent studies focused on the evolution from ordinary base-metal systems (sulfide-rich) to five-element vein

Structural incorporation of W6+into hematite and goethite: A combined study of natural and synthetic iron oxides developed from precursor ferrihydrite and the preservation of ancient fluid compositions in hematite

Autor: Ralph Steininger, Jörg Göttlicher, Gregor Markl, Mihail Tarassov, Stefan Kreissl, Ralph Bolanz

Publikováno v: American Mineralogist. 101:2701-2715

Hematite (α-Fe 2 O 3 ) and goethite (α-FeOOH) can incorporate considerable amounts of tungsten (W). Although W concentrations up to several wt% in hematite and goethite have been reported in the literature, none of the proposed models for a structu

The mineralogical variability of hydrothermal native element-arsenide (five-element) associations and the role of physicochemical and kinetic factors concerning sulfur and arsenic

Autor: Manuel Scharrer, Gregor Markl, Stefan Kreissl

Publikováno v: Ore Geology Reviews. 113:103025

The hydrothermal native element-arsenide mineralization comprises Ni-, Co-, and Fe-arsenides and -sulfarsenides, which typically form characteristic overgrowth textures on skeletal native silver and/or bismuth aggregates. Native arsenic, native antim
