WebDec 3, 2024 · Along with quartz and calcite, fluorite and barite are widespread at hydrous deposits of various genesis. Our database contains more than 48 000 measurements of quartz-hosted fluid inclusions, more than 6100 those in calcite, more than 5500 in fluorite, and more than 1200 in barite. WebHydrothermal fluid flow along fault zones in the Harz Mountains led to widespread formation of economic vein-type Pb-Zn ore and Ba-F deposits during the Mesozoic. We reconstruct the fluid flow system responsible for the formation of these deposits using isotope ratios (delta H-2 and delta O-18) and anion and cation contents of fluid inclusions ...
WebDec 30, 2016 · Fluorite, or calcium fluoride (CaF 2 ), another simple halide, is widespread in limestones that have been permeated by hydrothermal solutions containing the fluoride anion (Richardson and Holland, 1979 ).
