Compositions of magmatic melts and evolution of mineral

Melt and fluid inclusions were investigated in minerals from igneous rocks and ore (Au-Ag-Pb-Zn) veins of the Stiavnica ore field in Central Slovakia. High H2O (7.1–12.0 wt ) and Cl (0.32–0.46 wt ) contents were found in silicate melt inclusions (65–69 wt SiO2 and 5.2–5.6 wt K2O) in plagioclase phenocrysts (An 68–36) from biotite-homblende andesites of the eastern part of the
