Year of Discovery:1899

Physical Properties of Paralaurionite

Lustre:Sub-Adamantine
Diaphaneity (Transparency):Transparent
Colour:Colourless, white, yellow, violet, green
Hardness (Mohs):3

Crystallography of Paralaurionite

Crystal System:Monoclinic
Class (H-M):2/m - Prismatic
Space Group:P21/m {P1 1 21/m} {P21/m} {P1 21/m 1}
Cell Parameters:a = 10.79Å, b = 3.98Å, c = 7.19Å
β = 117.22°
Ratio:a:b:c = 2.711 : 1 : 1.807
Unit Cell Volume:V 274.57 ų (Calculated from Unit Cell)
Morphology:Crystals thin tabular {100} or lath-like by elongation [001]. The terminations of the plates or laths are rectangular or wedge-shaped as a result of development of pyramidal faces at the corners.
Twinning:Twin plane {100}, very common, as symmetrical contact twins with composition face (100), simulating orthorhombic holohedry.
Comment:OD structure.

Optical Data of Paralaurionite

Type:Biaxial (-)
RI values: nα = 2.050 nβ = 2.150 nγ = 2.200
Maximum Birefringence:δ = 0.150

Chart shows birefringence interference colour range (at 30µm thickness) and does not take into account mineral colouration.
Surface Relief:Very High
Dispersion:r < v strong
Pleochroism:Visible
Comments:Violet-tinted crystals are pleochroic with absorption Y is greater than X, Z.
Comments:Plates on {100} exhibit abnormal interference figures due to twinning.
