Résumé / Abstract

Compositional and paragenetic data are reported for cervelleite, ideally Ag⁴TeS, from three new occurrences in Romania: from Upper Cretaceous skarn mineralisation at Bāiţa Bihor, Northern Apuseni Mts. and Ocna de Fier, Banat, and from Neogene hydrothermal Au-vein mineralisation at Larga, Metalliferi Mts. Cervelleite from the two skarn occurrences contains significant amounts of Cu. Together with previously published compositional data, limited solid solution from Ag⁴TeS to approximately (Ag^3.2Cu^0.8)⁴TeS can be recognised. Closely associated with cervelleite in both skarn occurrences is an additional phase, Ag²Cu²TeS, which we believe is a possible new quaternary mineral in the Ag-Cu-Te-S system.
