Miniera di Isolagrande (Miniera Rio Siogna), Murialdo, provincia di Savona, Liguria, Italia
Old graphite mine, definitively closed in 1965, located in the area of Bric Camulera with numerous galleries opened in the little valleys of Rio Siogna, Rio Azzini, Rio Farian, Rio Maglia, Rio Botta, and Rio Euri.
Schröckingerite has been found in one of the galleries as tiny, yellow, brittle crystals showing a strong fluorescence. This mineral is not genetically related to the host rock, a Verrucano conglomerate with traces of graphite. Its genesis is probably due to the percolation of U-rich fluids origined from an upper horizon hosting an uranium mineralisation not discovered yet [Permian schists, similar to the U-bearing ones of the southern Cuneo Province (Piedmont) and Ponte Scalincio (Liguria), crop out outside the gallery].
