There are 33 luminescent minerals found in Langban, Varmland, Sweden included in the database.
Fluorescence Color similar to eucryptite for Wales UK specimens.
Mineral barite is one of the first luminescent materials from which the famous Bologna stone was obtained.
Nevertheless, up today the understanding of natural barite luminescence is very scarce.
It has been known for a long time that some specimens of barite are fluorescent under UV exposure and emit white, yellow, green or orange light.
In steady-state luminescence spectra of barite different luminescence bands from the UV to the red part of the spectrum have been detected.
However, only UO22+ and Eu2+ luminescence centers have been confidently identified (Tarashchan 1978; Gaft et al. 1985).
Laser-induced time-resolved technique enables to detect Ag+, Bi2+, Bi3+, Eu2+, Eu3+, Ce3+, Nd3+, (UO2)2+ and several still not identified emission centers (Gaft et al. 2001, 2008b)
Difficult to recognize from associated minerals, so fluorescence description is sometime subject to caution. For exemple in Nentsberry Haggs Mine, Alston Moor, Eden, Cumbria, United Kingdom barytocalcite is described as fluorescing Pink SW, associated with Witherite fluorescing White SW+LW and Phosphorescent by some authors and fluo White SW associated with calcite fluorescing red by others...;
Associated with orange red fluo calcite or red fluo Tilasite (Langban);
Grains of pure yellow Berzeliite show a red fluorescence under shortwave and no longwave fluorescence. So it is not the fluorescence of calcite through the berzeliite which is seen on shortwave. (?)
It seems that the Berzellite which gives a response under SW is Zn-bearing. The fluorescence color is green under SW. (info: S. Stolze)
Bustamite from Sterling Hill is not fluorescent. Bustamite from Franklin is mostly not fluorescent but sometimes.
Easily confused with NORBERGITE which is visually very similar to it.
The Crazy Calcite fluo red SW from Franklin, USA is sometime composed by dark red SW fluorescing Dolomite mixed with bright red SW fluorescing Calcite, with black Franklinite and tiny yellow Diopside crystals. The LW response is in shades of red-pink. It is however possible that the fluorescence of dolomite is due to the observation of the phenomenal fluorescence of calcite by transparency.
Samples from Langban are sometimes considered as mislabeled and could be mimetite.
Sometime intimately associated with margarosanite in Franklin; the margarosanite could therefore be responsible for the blue luminescence.
Other locality: Andover
The arsenate analogue of Hydroxylapatite. The OH analogue of Turneaurite.
In Jakobsberg, Sweden, wolastonite and margarosanite replace barysilite (see picture by Kjell Gatedal in bibliography)
Sometimes Langban samples are confused with hedyphane
Luminescence of pectolite was noted in 1903 by Kunz and Baskerville.
In Mt-St-Hilaire, Pectolite could be confused with Makatite. The major distinguishing feature is the fluorescence. While not all makatite fluoresces, when it does it is moderate to strong blueish white or very pale greenish SW (and sometimes LW as well) and pectolite is fluorescing in pink or orange.
The tungstates of calcium, strontium, magnesium and zinc, and the molybdates of calcium are known to show luminescence upon excitation by cathode rays or short-wave ultra-violet radiation. It is commonly assumed that this luminescence is characteristic of the tungstate and molybdate groups. The reason why other tungstates and molybdates are found to be non-luminescent is probably the temperature-quenching (see Nature article by F. A. Kröger in 1947 in the bibliography).
Associated with dull red fluorescing tilasite in Langban.
Associated with orange fluorescing svabite in Langban;
The arsenate analogue of Chlorapatite.
The Ca analogue of Hedyphane.
