Gonnardita
Sign in to saveGonnardite is a comparatively rare, fibrous zeolite, natrolite subgroup. Older papers claim that a complete solid solution exists between tetranatrolite and gonnardite, but tetranatrolite was discredited as a separate species in 1999. A series, based on the disorder of the silicon-aluminum in the framework, appears to exist between Na-rich gonnardite and natrolite, Na2(Si3Al2)O10·2H2O.

La gonnardita es un mineral de la clase de los tectosilicatos, y dentro de esta pertenece al llamado grupo de las zeolitas -subgrupo de la natrolita-. Fue descubierta en 1871 por el mineralogista francés Ferdinand Gonnard, La Chaux de Bergonne, Gignat, Puy de Dôme (Francia), que la llamó mesole, que podía confundirse con el de otro mineral. En 1896, Alfred Lacroix le cambió el nombre por el de gonnardita, en honor de su descubridor.
