Abstract
Studované minerály z vrtu Ja-9 (jv. od Frýdku-Místku) vykazují teploty homogenizace fluidních inkluzí v rozsahu 31-157 C. Fluida typu Ca-Na-Cl měla vyšší salinity a společně s údaji o stabilních izotopech naznačují, že se vyvíjela z mořské vody.
Abstract (in English)
Formation conditions of the base metal sulphide mineralization found in Ja-9 borehole (10 km SE from Frýdek-Místek, NE Moravia) have been investigated. Homogenization temperatures of the fluid inclusions in sphalerite, quartz and calcite range between 31 and 157 C. Minerals precipitated from Ca-Na-Cl fluid with higher salinities between 9 and 19 wt. % NaCl equiv. Isotopic composition indicates marine origin of the mineralizing solutions. Combined fluid inclusion and sulphur isotope thermometry allow to estimate pressure condition as high as 30 MPa. This value corresponds with a present-day position of the studied sample in depth 1085 m.
