NaMg4(AsO4)3
Colour:
beige, pale brownish, brownish-yellowish or greyish-brownish
Lustre:
Vitreous
Hardness:
Specific Gravity:
3.816 (Calculated)
Crystal System:
Tetragonal
Name:
Named for being the arsenic analogue of udinaite.
Isostructural with:
Known synthetic analogue. The As analogue of udinaite. First purely sodium-magnesium anhydrous arsenate mineral. Chemically somewhat related to badalovite, berzeliite, calciojohillerite, magnesiohatertite, and paraberzeliite. Compare also 'Unnamed (Na-Mg Arsenate Hydroxyarsenate)'.

Visually indistinguishable from udinite.

Optical Data of ArsenudinaiteHide

Type:
Uniaxial (-)
RI values:
nω = 1.777(10) nε = 1.820(6)
Max. Birefringence:
δ = 0.043
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
