  • Tetranatrolite: Mineral information, data and localities.

    www.mindat.org/min-3925.html Tetranatrolite was discredited in 1999 (but apparently without actually working on the type specimen or on any positively identified tetranatrolite itself). Tetranatrolite was originally reported from Poudrette quarry (Demix quarry; Uni-Mix quarry; Desourdy quarry), Mont Saint-Hilaire, Rouville Co., Québec, Canada.

  • Tetranatrolite (TL)

    www.saint-hilaire.ca/en/tetranat.htm A recent paper in the American Mineralogist has called for the discreditation of tetranatrolite in favour of gonnardite. The paper could validate tetranatrolite as gonnardite for all but 4 locations, of which MSH is one. Another paper, soon to be published, on the crystal structure of tetranatrolite seems to validate the species.

    pubs.er.usgs.gov/publication/70022099 The structure of tetranatrolite from Mont Saint-Hilaire, Quebec (U.S. National Museum sample R1830) with a = 13.197(7) A, c = 6.630(9) A, and space group I42d, was refined using single-crystal X-ray data. A representative formula of tetranatrolite determined from electron microprobe analysis is Na12.50K0.01Ca2.93Sr0.11Al19.09 Si20.91O79.74??nH2O.

  • Gonnardite - Wikipedia

    en.wikipedia.org/wiki/Gonnardite Gonnardite 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, Na 2 (Si 3 Al 2)O 10 ·2H 2 O.

We therefore Þ nd that paranatrolite is indeed a distinct mineral species, which can be formed at high pressure either from natrolite or tetranatrolite with a stability Þ eld that varies with composition.
