MINERALOGIE ŽELEZNÝCH RUD TYPU LAHN-DILL NA LOKALITĚ „DRAKOV“ U HEŘMANOVIC
Vol.7,(2000)
Abstract
Keywords:
Vrbno Group; iron ores; mineralogy; petrography
Iron ores of the Lahn-Dill type were mined at several localities near Heřmanovice in the northern part of the Vrbno Group. In the dump material at the locality „Drakov“, the fragments of ores composed of chlorite of the clinochlore-chamosite series were found. Chlorite schists and chlorite-muscovite to muscovite-chlorite schists as well as marbles from the studied locality usually contain magnetite as an accessory mineral. Its content reaches nearly 5 vol.% in the magnetite-richest samples of those found in the dump material and therefore the mentioned rocks may not to be used as iron ores.
