System:OrthorhombicColour:pale honey-yellow, ...
Hardness:3 - 4
Member of:Xonotlite Group
Name:Honouring the Canadian collector and mineral dealer Gilles Haineault (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).

Classification of Haineaultite
