Článek v PDFScorodite FeAsO4·2H2O from Jezdovice near Třešť
In the Jezdovice area (Jihlava ore district) the silver ores were exploited from the mid- 13th century up to the 18th century. The locality is hosted by cordierite-biotite gneisses of Moldanubian zone. The deposit is formed by hydrothermal mineralization, including quartz veins with Fe-sphalerite, galena, pyrite, arsenopyrite, pyrrhotite and chalcopyrite. Scorodite was found on old dumps near Jezdovice-Práchovna. The mineral was identified by X-ray powder diffraction, refined unit-cell parameters of scorodite correspond to the published values. The occurrence of scorodite in Jezdovice is the first in the Jihlava mining district.
