Alternatively:

(Na₃Na₃Na₃Na₃Na₃)Ca₆(^IVFe²⁺₃)Zr₃[Si₃O₉]₂[Si₉O₂₇SiO][Si₉O₂₇SiO]Cl(H₂O)
This updated formulation attempts to better illustrate structural relationships to other members of the group (and is also charge-balanced).

Colour:

Variable: Carmine-red, orange-red, orange, pink, cherry-red, brownish-red, yellowish-brown, brown, yellow, violet, green

Lustre:

Vitreous, Dull

Hardness:

5 - 6

Specific Gravity:

2.74 - 3.1

Crystal System:

Trigonal

Member of:

Eudialyte Group

Name:

From the Greek for "readily decomposable," in allusion to its easy solubility in acids.

Type Locality:

ⓘ Kangerluarsuk Fjord, Ilímaussaq complex, Kujalleq, Greenland

Principal member of the Eudialyte Group.

Note: most "eudialyte" photos on Mindat probably show unanalysed material and should be labelled "Eudialyte Group" since they might represent not eudialyte sensu stricto, but any of the various other members of the eudialyte group.

Fracture:

Irregular/Uneven

Density:

2.74 - 3.1 g/cm³ (Measured)

Optical Data of EudialyteHide

Type:

Uniaxial (+/-)

RI values:

n_ω = 1.606 - 1.61 n_ε = 1.61 - 1.613

Max. Birefringence:

δ = 0.003 - 0.004
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.

Thickness: 30 µm Order divisions

Rotation:

Surface Relief:

Moderate

Pleochroism:

Weak

Comments:

O= colorless, pale yellow, pink
E= pink to colorless
