System:OrthorhombicHardness:4 - 5
Name:For French mineralogist Ferdinand Gonnard (1833-1923).


Zeolite Group. Natrolite Subgroup.

The compositions and structural relationshp between gonnardite and tetranatrolite remains controversial (Artioli and Galli 1999; Evans et al. 2000; Ross, et al 1992; Lee, Y., et al. 2006).
