About Haineaultite
Gilles Haineault
Formula:
(Na,Ca)5Ca(Ti,Nb)5(Si6O17)2(OH,F)8 · 5H2O
Colour:
Pale honey-yellow, colourless to white, pale orange
Lustre:
Vitreous
Hardness:
3 - 4
Specific Gravity:
2.28 (Calculated)
Crystal System:
Orthorhombic
Member of:
Name:
Named in 2004 by Andrew M. McDonald and George Y. Chao in honor of Canadian mineral collector and mineral dealer Gilles Haineault [June 16, 1946 - ], prolific collector and authority on the minerals of Mont Saint-Hilaire.
The structure of haineaultite contains double dreier chains of SiO4 tetrahedra, which are linked by Ti cations into a three-dimensional framework. A topologically identical framework is found in the structures of chivruaiite, zorite (the Na-analogue of haineaultite) and the synthetic zorite analogue ETS-4 (Men'shikov et al., 2006).

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.

This shows the grain boundary and Becke line effect under plane-polarised
light, based on the contrast between this mineral's average refractive
index and the mounting medium. It does not take into account mineral
colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure
- the conoscopic view for a grain cut perpendicular to the acute bisectrix, using
this mineral's 2V. The two small white dots mark the melatopes - the points
where the two optic axes emerge - and are shown only when they fall within the
field of view. The coloured bands are isochromatics, and the dark bands are
isogyres.
Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
