Different distribution of selenides in the Bohemian Massif is mostly probably caused by different composition of the reservoir entering the fluid forming the minerals and partly by the different host rock. Enormous predominance of Cu is visible in the Western Moravia, documented by berzelianite, umangite and eskebornite as the most abundant Se-phases. Příbram and Zálesí are characterized by clausthalite as the most abundant Se-phase, in Příbram clausthalite is followed by abundant berzelianite, eucairite and umangite. Determination of succession of the selenides in Příbram and Zálesí is fairly complicated, due to material used for the studies, which was mostly collected as fragments from the dumps. However we can remark that, in both localities are visible increasingly higher amounts of Ag and Hg (also Sb in Příbram and Bi in Zálesí) in selenium mineralization compared to the Western Moravia. Příbram is also characterized by wide substitution by sulphur in selenides and rare Ag, Hg, Sb, As, Cd, Zn bearing selenides. In contrast with Příbram, the Zálesí is distinguishable by numerous of rare Bi bearing selenides. Nevertheless the most evolved and fractionated selenium mineralization is visible in Předbořice, where presence of PGE elements is indicated by merenskyite, the level of fractionation is also recorded by presence of rare selenides bearing Ag, Au, Pd, Te and Ni, which are mostly distinct in other studied localities.
