Locality type:
Mine
Classification
Species:
Igelströmite
Formula:
Fe3+(Sb3+Pb2+)O4
Comments:
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).
