...Stefan Graeser; Andreas Edenharter Abstract Jentschite, TlPbAs 2 SbS 6 , is a new sulphosalt mineral from the famous Lengenbach locality (Binntal, Switzerland). It was discovered in association with numerous other Tl-As-sulphosalts such as hutchinsonite, wallisite-hatchite, edenharterite...

... smithite, realgar, hatchite and probable trechmannite, edenharterite, jentschite and two unidentified sulfosalts. Raberite is opaque with a metallic lustre and has a dark brown–red streak. It is brittle with a Vickers hardness (VHN 10 ) of 52 kg mm −2 (range 50–55) corresponding to a Mohs hardness of 2½–3...

... with abundant realgar, and various other sulfosalts, mainly Tl-bearing species such as hutchinsonite, hatchite, and jentschite. Sicherite is orthorhombic, space group Pmnb , Z = 4, a = 12.479(3), b = 15.522(4), c = 5.719(4) Å; V = 1107.8(6) Å 3 . The strongest powder diffraction lines [ d obs (Å), ( hkl ), I...

... an increased level of substitution would bring a structural change like in the case of the two Tl-sulfosalts edenharterite TlPbAs 3 S 6 ( Graeser & Schwander 1992 ) and jentschite TlPbAs 2 SbS 6 ( Graeser & Edenharter 1997 ), where the ordered distribution of Sb in the structure led to a lowering...

... layers), particularly represented by members of the hutchinsonite merotypic series (bernardite, hutchinsonite, edenharterite, jentschite, imhofite). Other minerals belonging to this type are sicherite, gabrielite and ernigglite. Possibly, the recently described mineral raberite could be classified within...

... SbS 15 , is a new mineral from Lengenbach quarry, Binn Valley, Valais, Switzerland, one of the world’s premiere localities for Tl-bearing sulfosalts, the type locality for Tl species imhofite, erniggliite, edenharterite, stalderite, jentschite, sicherite, gabrielite, and dalnegroite. Raberite has been...

... , and its isotypic derivative jentschite, TlPbAs 2 SbS 6 × 3 = Tl 3 Pb 3 As 6 Sb 3 S 18 , which have similar chemical formulae but distinct crystal structures, belong to the group no. 5.1 of the hutchinsonite merotypic series ( Makovicky 1997 ). Relatively to baumhauerite, Pb 6 As 8 S 18...
