Meta-Autunite, Gummite (Vandendriesscheite, Soddyite, Parauranophane, Phosphuranylite) Uraninite. The orange Gummite has fused the Mica together in this case and there is a beautiful differentiation between the UV green glow of the Meta-autunite and the yellowish glow of the Uranophane crust. A rare and spectacular piece for the locality and a unique form of material that I have rarely seen.
