Abstract
Sulphide mineralization was found in relics of mine dumps from medieval mining near Utín, at SE part of the Havlíčkův Brod ore district (Bohemian-Moravian Highlands, Czech Republic). It is represented by pyrite, Fe-rich sphalerite, chalcopyrite, arsenopyrite, galena (with chemical compositions corresponding to other occurrences of this ore district) and more rare jamesonite and boulangerite. The main Ag ore was probably Ag-rich member of tetrahedrite group - kenoargentotetrahedrite-(Fe) with empirical formula (Ag5.45Cu4.48)Σ9.93(Fe1.75Zn0.32Mn0.01)Σ2.08Sb4.00S12.05. Another interesting mineral found in this association is Au-rich silver with Au contents in the range 53.35 - 56.40 wt. % and average empirical formula Ag0.60Au0.39. Schultenite, minerals of the pharmacosiderite group and inhomogeneous Fe-arsenates were detected from the rarely represented supergene mineralization.
