Routhierite is a rare thallium sulfosalt mineral with formula Tl(Cu,Ag)(Hg,Zn)2(As,Sb)2S6.
It was first described in 1974 for an occurrence in the Jas Roux deposit in the French Alps.[2] It was named after French geologist Pierre Routhier (1916–2008).[5] It is also reported from the Northern Ural Mountains, Russia and the Thunder Bay district of Ontario, Canada .[1]
