About Bussyite-(Ce)Hide

04905310017272471391155.jpg
Antoine A. B. Bussy
Formula:
(Ce,REE)3(Na,H2O)6MnSi9Be5(O,OH)30F4
Colour:
Pale pinkish orange
Lustre:
Vitreous
Hardness:
4
Specific Gravity:
3.00
Crystal System:
Monoclinic
Name:
Named J.D. Grice, R. Rowe, G. Poirier, A. Pratt, J. Francis in 2007 in honor of Antoine Alexandre Brutus Bussy (29 May 1794, Marseille, France – 1 February 1882, Paris, France), chemist, who is co-credited in isolating the element beryllium, which is a component of this mineral, in August 1828. The "-(Ce)" suffix is in allusion to cerium being the dominant rare earth element in the species.
The Ce analogue of bussyite-(Y).

Optical Data of Bussyite-(Ce)Hide

Type:
Biaxial (-)
RI values:
nα = 1.574(2) nβ = 1.591(2) nγ = 1.597(2)
2V:
Measured: 63° (2), Calculated: 61°
Max. Birefringence:
δ = 0.023
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. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.

Surface Relief:
Moderate
Optical Extinction:
X ∧ c = 39° (β acute); Y = b; Z ∧ a = 44.5° (β obtuse).
