A new occurrence of minerals of the kobellite-tintinaite series was recently discovered at the Majerská dolina siderite-type hydrothermal ore occurrence near Čučma, Spišsko-gemerské rudohorie Mts., Rožňava Co., Košice Region,

is ranging from 1.91 to 2.00 and the Sb/(Sb+Bi) atomic ratio in three studied samples varies between 0.41 and 0.52, hence corresponding mostly to Sb-rich kobellite, with a few analyses representing Bi-rich tintinaite.

A new occurrence of tintinaite was recently discovered at the Gašpar (Grexa) siderite-type hydrothermal vein with sulphides located in the Rožňavská dolina valley near Rožňava, Spišsko-gemerské rudohorie Mts., Rožňava Co., Košice Region, Slovakia. Tintinaite occurs as lead-gray, acicular to prismatic crystals up to 4 cm long or rich fibrous
aggregates and nests reaching up to 7 × 5 cm, which are enclosed in quartz-siderite gangue. Crystals and aggregates of tintinaite are often directly associated with massive accumulations of older sulphides, especially arsenopyrite, chalcopyrite, pyrrhotite and pyrite. Grains and aggregates of younger native bismuth or bournonite are occasionally
replacing aggregates of tintinaite. The refined unit-cell parameters of tintinaite (for the orthorhombic space group Pnnm) are: a 22.523(7) Å, b 34.137(11) Å, c 4.0389(14) Å and V 3105.4(1) Å3. The calculated value of N for tintinaite from the Gašpar vein is ranging from 1.93 to 2.00 and the Sb/(Sb+Bi) atomic ratio in three studied samples varies between 0.49 and 0.60, corresponding to Bi-rich tintinaite, with only one spot representing Sb-rich kobellite. The average Cu+Fe content in tintinaite is 1.96 apfu and minor concentrations of Ag (up to 0.14 apfu) and Se (up to 0.22 apfu) were also detected. The average (n = 55) empirical formula of tintinaite based on sum of all atoms = 63 apfu is (Pb10.56Ag0.07)10.63(Cu1.12Fe0.85)1.97(Sb8.50Bi6.75)15.25(S35.01Se0.15)35.16. Bournonite is rare and it forms anhedral grains or aggregates up to 220 μm, which are replacing aggregates of tintinaite. Its average (n = 8) empirical formula of bournonite based on sum of all atoms = 6 apfu is Pb0.99Cu1.00(Sb0.98Bi0.03)1.01(S2.99Se0.01)3.00.

New samples of jaskólskiite were recently collected at the Aurélia II siderite-type hydrothermal vein with sulphides near Rožňava, Spišsko-gemerské rudohorie Mts., Rožňava Co., Košice Region, Slovakia. It forms lead-gray, irregular aggregates up to 1.5 × 1 cm in size, which are enclosed in quartz-siderite gangue. Aggregates of jaskólskiite are consisting of individual, subhedral acicular crystals to 2 mm long, strongly replaced by younger bournonite and associated with Bi-rich jamesonite, tetrahedrite-(Fe), tintinaite, native bismuth and ullmannite. Significant variation of Cu (from 0.04 to 0.23 apfu) and Bi contents (from 0.32 to 0.77 apfu) was observed in studied sample. The average (n = 69 analyses) empirical formula of jaskólskiite from Rožňava-Aurélia vein based on Pb+Bi+Sb = 4 apfu is corresponding to Pb2.11Cu0.13(Sb1.42Bi0.47)1.89S5.14. Bi-rich jamesonite is the most common sulphosalt at the studied locality and it forms prismatic crystals up to 2 cm or irregular aggregates to 3 cm in size. The Bi content in jamesonite is ranging between 0.49 to 1.69 apfu. Bournonite is also common and two compositional types were distinguished. The first, dominant type is represented by Bi-rich bournonite (containing up to 0.14 apfu Bi). The second type of bournonite, represented by thin ribbons shows significant enrichment in As (reaching up to 0.49 apfu), but has only minor content of Bi (up to 0.08 apfu). Tintinaite is rare and its average (n = 9) empirical formula based on sum of all atoms = 63 apfu is corresponding to (Pb9.67Ag0.06)9.73(Cu2.55Fe0.40Zn0.07)3.02(Sb10.19Bi5.37)15.56S34.59Cl0.10.

A new occurrence of nuffieldite was recently discovered in a siderite-type hydrothermal vein with sulphides in Došťavná near Slovinky, Spišsko-gemerské rudohorie Mts., Spišská Nová Ves Co., Košice Region, Slovakia. It forms lead-gray acicular crystals reaching up to 1 cm in size or aggregates up to 2.5 cm, which are enclosed in quartz-siderite
matrix together with chalcopyrite, pyrite, tourmaline and chlorite. Nuffieldite is frequently replaced by minor aikinite, galena and native bismuth. The refined unit-cell parameters of nuffieldite (for the orthorhombic space group Pbnm) are: a 14.5313(16) Å, b 21.454(2) Å, c 4.0500(6) Å and V 1262.58(19) Å3. The average (n=145 analyses) empirical formula of nuffieldite from Slovinky-Došťavná based on Pb+Bi+Sb = 5 apfu is corresponding to Cu1.30Pb2.00Bi2.00(Pb0.30Bi0.30Sb0.40)1.00(S7.12Se0.03)7.15. Aikinite forms microscopic, anhedral to subhedral grains or aggregates replacing nuffieldite. The average (n=29) empirical formula of studied aikinite based on (Cu+Pb)/2+(Sb+Bi) = 8 apfu is Pb3.83Cu3.76(Bi4.12Sb0.09)4.21(S12.40Se0.03)12.03.
An interesting assemblage of bismuth and complex lead-bismuth and lead-antimony sulfosalts have been identified in samples from hydrothermal quartz veins hosted in S-type granitic rocks at the Elisabeth mine near Gemerská Poloma, Slovakia. We provide the first detailed study of the chemical composition of sulfosalts from the hydrothermal veins directly related to the specialized (Sn-W-F enriched) Gemeric granites. Bismuthinite derivates (bismuthinite and phases with n aik ranging from 21.3 to 23.7 and 30.3), minerals of the kobellite-tintinaite series (with Sb/(Sb + Bi) atomic ratio ranging considerably between 0.13 and 0.71), giessenite-izoklakeite series (with Sb/(Sb + Bi) from 0.26 to 0.33) as well as Pb-Sb sulfosalts (mainly jamesonite, boulangerite, robinsonite and their Bi-rich varieties) are common. Rare Bi-enriched rouxelite, bournonite and minerals of the tetrahedrite group were also observed. The two distinct types of sulfosalts associations were distinguished, each related to the different type of host rock and with variable Bi/Sb ratio. The first is represented predominantly by Bi-rich sulfosalts (bismuthinite derivates, kobellite, giessenite-izoklakeite) and occurs in the quartz veins hosted in P-enriched leucogranite. The second association is developed only in hydrothermal quartz veins hosted in porphyric granites and except of Bi (bismuthinite derivates) also significant amounts of Sb-rich sulfosalts (tintinaite, boulangerite, robinsonite, jamesonite, rouxelite, bournonite and tetrahedrite-(Zn) to tetrahedrite-(Fe)) are present.
