About DussertiteHide

This section is currently hidden. Click the show button to view.
Formula:
BaFe3+3(AsO4)(AsO3OH)(OH)6
Colour:
Green, yellow-green, bluish green; yellowish green in transmitted light.
Hardness:
3½
Specific Gravity:
3.75
Crystal System:
Trigonal
Name:
Named in 1925 by Jules Barthoux in honor of Jean Baptiste Desiré Dussert (1872-1928), French mining engineer who worked in Algeria and General Inspector of Mines.
A secondary mineral and frequently an alteration product of arsenopyrite.
Some dussertite contains Sb replacing Fe (Kolitsch et al., 1999).

Closely related to the Unnamed (Fe-analogue of Weilerite and Ba-analogue of Oberwolfachite).

Optical Data of DussertiteHide

This section is currently hidden. Click the show button to view.
Type:
Uniaxial (-)
RI values:
nω = 1.87 nε = 1.845 n = 1.85
2V:
Measured: 15° to 20°
Max. Birefringence:
δ = 0.025
Based on recorded range of RI values above.

Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.

Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.

Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars.

Surface Relief:
Very High
Pleochroism:
Visible
Comments:
Shades of greenish yellow.
Comments:
May be anomalously biaxial at times with 2V = 15° to 20°.
