Luminescence, fluorescence and phosphorescence of minerals

BASSETITE

NOT FLUORESCENT but cited by some authors

Chemical Formula: Fe⁺²(UO₂)₂(PO₄)₂ 8H₂O

Familly: Phosphates, Arseniates, Vanadates

Status: IMA-GP

Mineral for Display: No

Luminescence:

UV Type	Main color	Intensity	Observation Frequency

Phosphorescence (in the common meaning of the term) seen by naked eye:

No Data

Comments:

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.

Main Activator(s) and spectrum:

Most Common Activator: (UO₂)²⁺(Uranyl ion) intrinsic

Other activators: ,

No spectrum for the moment

Best Locality for luminescence(*):

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) ;

(*)Data are not exhaustive and are limited to the most important localities for fluorescence
