Långban Mine, Långban Ore District, Filipstad, Värmland County, Sweden (original) (raw)

Description: There were at least 3 different finds of akrochordite made at Långban: Origially found as aggregtes of minuite sub-parallel crystals in small ammount in druses lined with unusually stable pyrochroite crystals and barite crystals. It was found in the "Japan" workings of the Långban mines, at a depth of about 100 meters. The first find consisted of seven specimens (Flink, 1922) The second type was of a handful of specimens with pale pink aggregates of Akrochordite to 2 mm with Eveite, Brandtite and an unknown Mn-arsenate. (Moore et al.,1989) A small find was also made on the dumps at the mine in the early 1990s consisting of very small (less than 1 mm) single crystals in fractures. (Knut Eldjarn, 2009)

Description: Based on Dunn et al (1985) and Biagioni et al (2019) only some of this fibrous/columnar material also knonw as "asbestos hedyphane" has been demonstrated via analyses to be (OH) dominant. Consequently, unanalyzed specimens should be posted under "Hedyphane group".

ⓘ Igelströmite (TL)

Formula: Fe3+(Sb3+Pb2+)O4

Type Locality:

Description: With a good probability, the specimens of the two new minerals originate from the Hindenburg working in the mine, where most of the nadorite specimens of the present type were encountered (Flink, 1923). The label assigned to the igelströmite type sample states the Japan drift, but this might be an error, a mere confusion through the association with Flink's no. 66. Hindenburg was mined for Fe and Mn ore at the 150 m level, from 1916 to 1928 and was finally worked through into the England stope at the 165 m level (Magnusson, 1930).
