Abstrakt (česky)
   Minerals found in dolomite veins cutting serpentine rocks around Letovice and its surroundings composed remarkably heterogeneous set which is different from any other locality in the Bohemian Massif. The composition of copper minerals (bornite, chalcocite, covellite, chalcopyrite), millerite, dolomite veins and magnetite is similar to the composition of their host ultrabasic rocks. Lead and bismuth (galena, native Bi) are considered in this environment as atypical. Parkerite and wittichenite are transitional . they consist of elements of both groups. Despite being impossible to determine detailed order of crystallization, it was implied by microscopic studies that sulphides Pb-Bi(Cu) are relatively older than copper minerals. Fe-Cr spinelides that are rarely found in dolomite veins on the outline of serpentine rock are possibly relicts of premetamorphic magmatic stage.
