Luminescence, fluorescence et phosphorescence des minéraux: fiche descriptive

BASSETITE

NOT FLUORESCENT but cited by some authors

Scheikundige formule: Fe⁺²(UO₂)₂(PO₄)₂ 8H₂O

Familie: Fosfaten, Arsenaten, Vanadaten

Status: IMA-GP

Mineraal om tentoon te stellen: Nee

Fluorescentie:

UV Type	Kleur	Intensiteit	Frequentie van de observatie

Fosforescentie (in de algemene betekenis) zien met het blote oog:

No Data

Commentaar:

Microscopic and microprobe study of polished sections resulted in identification of the supposed bassetite of the Jáchymov (Joachimsthal) ore district as a mixture of meta-autunite and amorphous Fe-hydroxides, which replaced the original U-mica. The pseudomorphs fluoresce mottled yellow in ultraviolet light. (see bibliography).But Bassetite itself is non-fluorescent.

Activator en spectrum:

Voornaamste Activator: (UO₂)²⁺(Uranyl ion) intrinsiek

Geen spectrum voor de moment

Beste vindplaats voor fluorescentie(*):

Jáchymov District (St Joachimsthal), Krušné Hory Mts (Erzgebirge), Karlovy Vary Region, Bohemia, Czech Republic (Not really Bassetite but a mix of Meta-Autunite and Fe hydroxydes) ;
