About GonnarditeHide

Ferdinand Gonnard

Formula:

(Na,Ca)₂(Si,Al)₅O₁₀ · 3H₂O

Colour:

White, yellowish to salmon-red

Lustre:

Silky

Hardness:

4 - 5

Specific Gravity:

2.25 - 2.36

Crystal System:

Orthorhombic

Member of:

Natrolite Subgroup > Zeolite Group

Name:

Named in honor of Ferdinand-Pierre-Joseph Gonnard (30 March 1838, Gannat, Allier, France - 16 October 1923, Lyon, Rhône, France), Professor of Mining Engineering at the University of Lyon, France. He wrote mineral summaries of regions of France and earlier found gonnardite, but described it as mesole (thomsonite). He also discovered dumortierite.

Type Locality:

ⓘ La Chaux de Bergonne, Gignat, Issoire, Puy-de-Dôme, Auvergne-Rhône-Alpes, France

Zeolite Group. Natrolite Subgroup.
Most gonnardites have a disordered natrolite framework.

The compositions of and structural relationships between gonnardite and tetranatrolite remain controversial (Artioli and Galli 1999; Evans et al. 2000; Ross et al. 1992; Lee et al. 2006).
