...Cristian Biagioni; Ferdinando Bosi; Ulf Hålenius; Marco Pasero Abstract The crystal structure of turneaureite, ideally Ca 5 (AsO 4 ) 3 Cl, was studied using a specimen from the Brattfors mine, Nordmark, Värmland, Sweden, by means of single-crystal X-ray diffraction data. The structure was refined...

... has important implications with respect to the chlorapatite-pyromorphite solid solution series. An analysis of compositions of natural members of the pyromorphite-mimetite-turneaureite-chlorapatite system suggests the existence of complete solid solution among pyromorphite, mimetite, hedyphane...

..., together with svabite, Ca 5 (AsO 4 ) 3 F, and turneaureite, Ca 5 (AsO 4 ) 3 Cl. Johnbaumite is topologically similar to the other members of the apatite supergroup: columns of face-sharing M 1 polyhedra run along c and are connected through T O 4 tetrahedra, giving rise to a zeolite-like microporous...
