ncat WD113 Cassiterite, Hyalite, Erongo Mountains, Karibib, Erongo, Namibia

October 29, 2020 Steve Africa Namibia

Nice sharp group of cassiterite crystals with a partial coating of fluorescent green hyalite opal. The hyalite fluoresces under longwave UV (Convoy) but is much brighter under shortwave. The green fluorescence is due to uranyl ions.
