Name:"Thio" = sulphur and spinel in allusion to the member species's chemical composition as sulphides (and related minerals such as selenides, tellurides, etc.) and their spinel-like structure.


A group of sulphides and related minerals (X = S, Se, Te) with a spinel structure (compare the Spinel Group of oxides).
