Bismuth and bismuth-antimony sulphosalts from Kutna Hora vein Ag-Pb-Zn ore district, Czech Republic

Popis výsledku v původním jazyce

A new, previously unknown association of Pb-Bi-Sb-Ag sulphosalt minerals has been found in samples from mine dumps of the Staroceske pasmo Lode of the Kutna flora Ag-Pb-Zn ore district, central Bohemia, Czech Republic. These minerals form polymirteral aggregates up to 1-3 cm in quartz or base sulphides. Apart from numerous members of lillianite homologous series, new occurrences of aramayoite, bismuthinite, cosalite, ikunolite, izoklakeite, matildite, galena,,, Bi-rich jamesonite, Bi-rich boulangerite, Bi-rich owyheeite and Bi-rich semseyite have been identified. An extraordinary extent of the Bi-Sb substitution is characteristic of the studied association. Bi-rich mineralization of this scope has not been previously known from the Kutna Hora ore district. The origin of this sulphosalt mineralization is related to the penetration of lower temperature fluids (c. 100-250 degrees C) into tectonically opened fractures in older ore veins filling. Virtually no mobilization of elements from the earlier vein filling took place; hydrothermal fluids must have been relatively rich in Ag and Ph and simultaneously poor in Cu. High Bi content was characteristic of the initial stage of the mineralization. Gradually, the Bi/Sb ratio decreased considerably with more Sb-rich minerals originating. At the final stage, Bi-rich Pb-Sb sulphosalts with lower A2 contents crystallized.
