Genetical peculiarities of the mercury indications near Sárospatak (Tokaj Mts., NE-Hungary) on the basis of fluid inclusion studies
The mercury indications are NNW from Sárospatak, in area bounded by Királyhegy, Cinegés and Botkő. The cinnabar occurrences are situated in the metasomatically altered Badeiiian rhyolite tuff. The primary and pseudosecondary fluid inclusions of barites from Királyhegy and secondary gas-liquid inclus...

| Tartalmi kivonat: | The mercury indications are NNW from Sárospatak, in area bounded by Királyhegy, Cinegés and Botkő. The cinnabar occurrences are situated in the metasomatically altered Badeiiian rhyolite tuff. The primary and pseudosecondary fluid inclusions of barites from Királyhegy and secondary gas-liquid inclusions of magmatic quartz grains from Botkő are studied. On the basis of fluid inclusion studies the barite crystals grew in a boiled paleohydrothermal system on temperatures 187± 13.1 °C and on pressures 6—20 bar. The solution composition was NaCl-CaCl2-H20 (-C02)-type with 2.31 ±0.55 NaCl equiv. wt % concentration values. The secondary gas-liquid inclusions of the magmatic quartz grains preserved the boiled hydrothermal fluids also and the diluted, post-boiling fluids, which had lower temperatures and concentration values. The crystallisation of cinnabar probably was in connection witn tne boiling and the temperature depression produced by mixing of the subsurface cold waters and the hot hydrothermal fluids. On the basis of the geological and the fluid inclusion data the mercury indications as a shallow zone of a polymetallic (±Au, Ag) ore deposit are explained. |
