Optical Data of Uranocircite

Type:Biaxial (-)
RI values: nα = 1.574 nβ = 1.583 nγ = 1.588
2V:Measured: 70° , Calculated: 72°
Maximum Birefringence:δ = 0.014

Chart shows birefringence interference colour range (at 30µm thickness) and does not take into account mineral colouration.
Surface Relief:Moderate
Dispersion:none
Pleochroism:Weak
Comments:X = Colourless
Y = Z = Pale canary yellow
Comments:Exhibits sets of twin lamellae parallel to {100} and {010}. The biaxial material, upon heating to 100° - 150°, transitions to uniaxial with the accompanying loss of water to the dihydrate.
