| Comments: | Kingsbury reference. Kingsbury (1965): "For many years the bismuth telluride tetradymite (Bi2T2S) has been accepted as a British species, but this status has never been satisfactorily established. It was originally thought to occur in Brandy Gill, Carrock Fell, Cumberland, though in 1858 Greg and Lettsom had stated that the mineral appeared to differ much in composition from other tetradymites. The Carrock mineral was later regarded as a new species and was named grünlingite, but further investigations have shown that these specimens are not all identical and probably represent several varieties or phases of the allied mineral joséite, with compositions near Bi4TeS2: none of them, so far, have proved to be tetradymite." |
