A very rich sample of reddish-brown beraunite crystals forming fan-like aggregates with light wavellite crystals and yellow cacoxenite on an Ordovician shale fracture. In places, open cavities contain perfectly delimited clusters of reddish beraunite (crystals are up to 2 mm long), overgrown with semi-transparent and yellowish, unusually isolated wavellite crystals. On some parts of the sample, there is also fluffy, dandelion-yellow cacoxenite, which is also younger than beraunite.
