Abstract (in english)
   Stefanite is the abundant sulfosalt in the Březové Hory, Bohutín, Třebsko, Lill, Háje deposits from the Příbram ore district, and a minor phase in the Ratibořské Hory, Stará Vožice, Poličany near Kutná Hora, Dolní Rožínka, Zálesí, Jáchymov, Měděnec and Vejprty. The X-ray diffraction study of stefanite from 14 localities was confirmed the existence of the Ribár and Nowacki (1970) stefanite cell and structure. Although copper is not a normal component of the stefanite structure, minor amounts of copper, up to 0.51 wt.pour cent is recorded n stefanite from Vejprty deposit. Stefanite does not normally form a soliid soluton series with an arsenic analog, and the arsenic values reached to 0.32 wt.pour cent. Keighin and Honea (1969) suggested that 197°C represents the maximum temperature of the stefanite stability. this conclusion is supported by the fact that stefanite is formed very late in the paragenetic sequenceis recroded in stefanite from Vejprty deposit.
