... ) 2 with Z = 16. Additional analytical data are presented for a magnussonite-like phase from the Brattfors Mine, Nordmark, Sweden. These lead to a very tentative formula, Mn 10 As 6 3 + O 18 Cl ( OH ) , with (OH) assumed for charge balance. This phase remains unnamed. Copyright © 1984...

...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...

...C. A. Francis; P. H. Ribbe Abstract The crystal structure of type manganhumite from the Brattfors mine, Nordmark, Sweden [(Mn 0.68 Mg 0.30 Fe 0.01 Ca 0.01 ) 7 (SiO 4 ) 3 (OH) 2 , Pbnm, a = 4.815(1), b = 10.580(2), с = 21.448(5)A] has been refined by conventional least-squares methods to R = 0.051...

..., a manganese arsenite first found at Långban in Sweden ( Gabrielsson 1956 ), was later identified at Sterling Hill. A compositionally closely related phase is also known from the Brattfors mine, Nordmark, Sweden ( Dunn & Ramik 1984 ). These phases are here described from the Garpenberg Norra mine...

... ; Frost and Weier, 2006 ), possibly due to the rarity of the mineral. Only a few occurrences are known worldwide: in veinlets through metamorphosed manganese deposits of the Moss and Brattfors mines, Nordmark (Sveden) and at Långban, Värmland (Sweden); in a metamorphosed stratiform zinc orebody...
