Research station, Terra Nova Bay
Formula:
(Na,Ca)8(Si68Al12)O160 · 29H2O
Colour:
Bluish
Lustre:
Vitreous
Specific Gravity:

Name:
Named for the Italian Antarctic Station at Terranova Bay, Antarctica.
Zeolite Group.

According to Galli et.al., "Terranovaite .... was found in only one of the Ferrar dolerite samples collected. The specimen is from the SW crest, just under the summit of Mt. Adamson (Lat. 73° 56'S, Long. 162° 56'E)."

Terranovaite, tabular, transparent and bluish, was closely associated with heulandite.

Optical Data of TerranovaiteHide

Type:
Biaxial (+)
RI values:
nα = 1.476(2) nβ = 1.478(2) nγ = 1.483(3)
2V:
Measured: 65° (5), Calculated: 65°
Max. Birefringence:
δ = 0.007
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.

Surface Relief:
Moderate
Dispersion:
r < v moderate
Optical Extinction:
X = c; Y = a; Z = b.
