... the Långban Mn–Fe deposit, Värmland County, Sweden. Margarosanite was later also found at the nearby Harstigen and Jakobsberg mines. Anthropogenic margarosanite occurs on corroded lead bullets (Mera et al. , 2015 ). Further studies on Franklin type specimens clarified the crystallography (Armstrong, 1963...

...}^{5+}Fe_{0.5}^{3+})O_{4}\) \end{document} , was described by Dunn et al. (1988) as a new spinel-related mineral from the Långban mine in the Filipstad district, Värmland, Sweden. A second occurrence of this rare species was reported from the Jakobsberg deposit of the same district by Holtstam...

...Dan Holtstam; Rolf Norrestam Abstract Lindqvistite is a new mineral from Jakobsberg, Filipstad, Sweden. It occurs as black crystals up to 5 mm in size with perfect basal cleavage, associated with hematite, jacobsite, plumboferrite, calcite, phlogopite, andradite, hedyphane, barite, and copper...

...Cristian Biagioni; Ferdinando Bosi; Ulf Hålenius; Marco Pasero Abstract The crystal structure of svabite, ideally Ca 5 (AsO 4 ) 3 F, was studied using a specimen from the Jakobsberg mine, Värmland, Sweden, by means of single-crystal X-ray diffraction data. The structure was refined to R 1 = 0.032...

...Dan Holtstam; Rolf Norrestam; Arne Sjodin Abstract Plumboferrite from the type locality at Jakobsberg, Filipstad, Sweden, has been reexamined. It occurs in assemblages confined to bands in metamorphic carbonate rock and is associated with hematite, magnesioferrite-jacobsite-magnetite solid...

...Gunnar Raade © 2000 Mineralogical Association of Canada 2000 The Långban dolomite-hosted iron–manganese deposit, situated in central Sweden, is one of the most mineral-rich sites in the world, with about 270 different species. It is the type locality of nearly 70 of these, and for more...

... Mn–Fe deposit in Sweden found Pb substitution for Ba (Holtstam et al. , 2021 ). Such substitution has not been reported in other mentioned localities ( Table 3 ). This occurrence is related to the mineral association because, in the Jakobsberg deposit, walstromite occurs together with margaro...

... as having residual, irregular cores of jacobsite. Two other occurrences of filipstadite were later reported at two other “Långban-type” Mn-Fe deposits, namely Jakobsberg and Nordmark, in south-central Sweden ( Holtstam 1993 ; Holtstam et al. 1998 ). At Jakobsberg the mineral coexists with hausmannite...
