3.1 Bukovite: revised formula

Recently, a paper was published (Journal of Geosciences, 68, 179–184, 2023) in which the chemical formula of bukovite was revised from Cu₄Tl₂Se₄ to (Cu₃Fe)Tl₂Se₄ based on a single-crystal structural study. From these data it was shown that copper and thallium occur in bukovite as Cu⁺ and Tl⁺; therefore the occurrence of some Fe³⁺ partially substituting for Cu⁺ at the unique M site is necessary for charge balance requirements. This represents a further case of valency-imposed double site occupancy. The chemical formula of bukovite has been modified in the IMA List of Minerals accordingly. This is an executive decision taken by the CNMNC officers.

3.2 Renaming of straßmannite to strassmannite

It was agreed to modify the name straßmannite to strassmannite, with “double s” instead of ß – the so-called “Eszett”, which is peculiar to the German alphabet. This is in keeping with a recent CNMNC resolution (Mineralogical Magazine, 87, 225–232, 2023) which aims at rationalizing the mineralogical nomenclature by abolishing Greek letters as well as Arabic and Roman numerals from mineral names. Straßmannite represented the unique case among mineral names in which the Eszett was employed instead of double s. Therefore, for the sake of analogy with fleisstalite, giessenite, günterblassite, mössbauerite, phosphorrösslerite, and rösslerite, the mineral straßmannite – which was approved only 6 years ago – is now renamed strassmannite. This is an executive decision taken by the CNMNC officers.
