Variská syntektonická fluida generovaná z paleozoických sedimentů Moravského krasu a Drahanské vrchoviny

Original language description

Variscan hydrothermal calcite/quartz, quartz/chlorite/calcite veins are widespread in Palaeozoic sedimentary sequences of the Moravian Karst and the Drahany Highland. Veins developed in two main lithological types, in limestones and siliciclastic rocks (greywackes, conglomerates, shales). The revealed variability in fluid types trapped in inclusions reflects the lithology of host rocks and/or structural aspects. The H2O-NaCl, CH4-CO2 and H2O-NaCl(-CH4) fluid systems are responsible for precipitation ofveins. Revealed temperatures (Th = 85-275C) point to regional trends. Some local conditions, however, differ from the trend. Within a shear zone, highly variable temperatures (up to 283C) and pressures (180-1200, max. up to 2040 bar) may result from friction overheating and pressure fluctuations along thrusts planes.
