... as écrinsite: baumhauerite, argentobaumhauerite, boscardinite and bernarlottiite. By comparison to the closely related boscardinite (ideally Tl 2 Pb 8 Sb 14 As 4 S 36 ), écrinsite is characterised by both an excess of As over Sb and a distinctly higher substitution of [(Tl,Ag) + (As,Sb) 3+ ] ↔ 2Pb 2...
