Description
Submillimeter, yellow and fibro-radiated crystals of kasolite and uranotile in millimeter patches on micro-quartz, all on a very “graphic” rock.
Specimen probably collected in the 1930’s in the mine exploiting a fluoro-barite vein in Wolsendorf, Rhineland Palatinate, Germany.
Mineralogical specimen sold in the 20th century by the naturalist merchant Deyrolle, based in Paris, with original label.
