Název v původním jazyce

Fluid inclusion study of the Horní Luby cinnabar deposit, Saxothuringian Zone, Bohemian Massif: clues for the metamorphic remobilization of mercury

Popis výsledku v původním jazyce

The stratiform deposit of mercury at Horní Luby near Cheb (Czech Republic) is hosted by Ordovician phyllites of Vogtland-Saxony Paleozoic Unit in the Saxothuringian Zone of the Bohemian Massif. Ore is represented by cinnabar disseminated within the phyllite and by lenticular bodies rich in massive cinnabar (lenses with a thickness of up to 1 m and length along the strike varying from less than 1 m up to 20 m). Cinnabar is accompanied by pyrite and locally also siderite. The P-T history of the mineralization was deciphered by the study of fluid inclusions. Early fluids are fluid trapped in secretion quartz. This fluid underwent several heterogenization events starting from approximately 300 oC and continued down to 200-150 oC. Metamorphic quartz of secretion origin crystallized at ~300 oC, while hydrothermal pyrite crystallized at 220-210 oC and cinnabar at 195-160 oC. The formation of the richest ore was associated with the replacement of metamorphic quartz in phyllites by the cinnabar
