Locality type:Quarry
Classification
Species:Chamosite
Formula:Fe52+Al(AlSi3O10)(OH)8
Comments:Blaß et al. (2021, p. 12) has one photo of a yellowish aggregate < 0.5 mm on a todorokite matrix.
Chamosite is found regularly in rocks that have manganese minerals like todorokite. It forms greenish-brownish yellow irregular spherical and worm-like aggregates; also massive.
Both the EDX and the XRD results were a good match with standard chamosite.
