Abstract/NotesThalcusite from a new locality in the Ilímaussaq complex, the Nakkaalaaq mountain, occurs in a coarse ussingite–aegirine vein and is associated with sphalerite and cuprostibite. The empirical composition is Tl1.89K0.08Cu2.86Fe1.34S4.00. Secondary tenorite–Sb oxide aggregates are developed along cleavages. Tarnish products are essentially pure Cu+ sulphide. All three layered thallium sulphides from the Ilímaussaq complex, thalcusite, chalcothallite and rohaite, contain K substituting for Tl. Varieties with K > Tl were not found in the massif.
