...Adam Pieczka; Bożena Gołębiowska Abstract We describe a complete sequence of cuprobismutite homologues (kupčikite, hodrušite, cuprobismutite and an unnamed N = 2.5 homologue) coexisting with one another, generally in the form of coherent, lamellar intergrowths, found in a granitic pegmatite cutting...

...Stanislav Jeleň; Jaroslav Pršek; Vladimir A. Kovalenker; Dan Topa; Jiří Sejkora; Martin Števko; Daniel Ozdín Abstract An interesting association of the Bi sulfosalts was identified in the Rozália mine, Hodruša–Hámre, Slovakia. Sulfosalts of the cuprobismutite series are the most common, and occur...

...Jaroslav PRŠEK; Tomáš MIKUŠ; Emil MAKOVICKY; Martin CHOVAN Abstract Three sulphosalts from the cuprobismutite homologous series have been found in a hydrothermal Ni-Bi-As mineralization at Čierna Lehota (Slovakia). Kupčíkite (second world occurrence) has a significant content of Pb (2.73 wt...

...C. L. Ciobanu; A. Pring; N. J. Cook Abstract Coherent intergrowths, at the lattice scale, between cuprobismutite ( N = 2) and structurally related paděraite along both major axes (15 Å and 17 Å repeats) of the two minerals are reported within skarn from Ocna de Fier, Romania. The structural...

...Dan Topa; Emil Makovicky; Tonči Balić-Žunić Abstract Crystal structures of natural cuprobismutite, Cu 8.05 (Bi 12.83 Ag 0.96 Pb 0.15 Cd 0.08 ) ∑14.02 S 23.93 , from Felbertal, Austria, with a 17.590(4), b 3.922(1), c 15.177(3) Å, β 100.710(4)°, space group C 2/ m , Z = 1, and of two samples...

...Nigel J. Cook; Cristiana L. Ciobanu Abstract An assemblage consisting of bismuthinite derivatives, mainly in the range gladite – oversubstituted bismuthinite (Cu 0.833 Pb 0.833 Bi 19.167 S 30 ), makovickyite, and intergrowths of cuprobismutite and paděraite, with minor hodrushite, occurs...

...Charles Palache Abstract Examination of the type specimen of cuprobismutite upon which Hillebrand founded the species was made possible by the loan of the specimen (U.S.N.M. 92902) by the U. S. National Museum. This examination revealed the definite occurrence in it of two minerals, bismuthinite...

..., molybdénite, sphalérite et bismuth natif, en intercroissances avec la makovickyite, la cupromakovickyite, la hodrushite, la cuprobismutite et des dérivés de la série bismuthinite–aikinite. Il s’agit d’un minéral gris avec éclat métallique, cassant, et sans clivage. En moyenne, les micro-indentations...
