... ) 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...

.... The earliest complex borates are takéuchiite (1179 bits), blatterite (1656 bits), and the Mg analogue of blatterite (1612 bits), which are reported uniquely from 1825 Ma deposits at Långban and Nordmark (Sweden). There is little evidence for a significant increase in maximum structural complexity since 1825 Ma...

...Ulf Hålenius; Ferdinando Bosi Abstract A natural yellow and transparent crystal of Mn-bearing, Mg-rich gahnite (ZnAl 2 O 4 ) from Nordmark (Sweden) was studied by electron microprobe, single-crystal X-ray diffraction and optical absorption spectroscopy. The empirical structural formula...

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...

...L. G. Berry; A. R. Graham Abstract New observations on brackebuschite from Sierra de Cordoba, Argentina, and on hema-tolite from the Moss mine, Nordmark, Sweden, combined with existing chemical analyses yield the following descriptions of these minerals. Copyright © 1948 by the Mineralogical...

...Clifford Frondel Abstract Manganosite from Franklin, New Jersey, contains exsolved plates of zincite oriented with zincite {0001} [10 1 0] parallel to manganosite {111} [011].

...Cornelius S. Hurlbut, Jr. Abstract Synadelphite, essentially a hydrous arsenate of manganese and aluminum, was described as a new species from Nordmark, Sweden, by Sjogren (1884 A). The description of the new species was extended and modified by Sjogren (1884 B; 1885) and Hamberg (1889...

... skarn in the Långban Mn-Fe deposit, central Sweden. The major skarn minerals comprise Ba-rich potassium feldspar, albitic plagioclase, Pb-rich scapolite, and phlogopite, while Pb-rich epidote, vesuvianite, and calcic garnets are minor phases. The vesuvianite grains are intensely zoned displaying Bi-rich...

...Uwe KOLITSCH; Dan HOLTSTAM; Kjell GATEDAL Abstract A new occurrence of the rare arsenate species gasparite-(Ce), ideally CeAsO 4 , is reported from the Kesebol Mn-Fe-Cu deposit in south-western Sweden, where it occurs as yellowish euhedral crystals up to 0.5 mm in maximum size, in association...

...A. G. Christy; K. Gatedal Abstract We report preliminary petrographic and mineral chemical data for a rock hosting an unusual mineral assemblage from Långban, Värmland, Sweden.

... ), and to allactite from Moss Mine, Nordmark, Sweden (JCPDS 17-748). The calculated unit-cell parameters (Table 2 ) differ little from those reported for allactite in the literature ( Palache et al ., 1951 ; Moore, 1968 ). Energy-dispersive microanalysis of a crystal fragment (#332631) showed Mn and As plus...
