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).
