Zeolites are microporous aluminosilicate minerals such as analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite.
In the group of Na-bearing minerals, natrolite was stable at low temperature and replaced by analcime above 100[degrees]C, followed by albite above 200[degrees]C.
The mineral part of analysed samples is composed of clays, feldspars, carbonates, analcime, natrolite, quartz and bassanite (Table 1).

26.) His description is easy to follow, and he noted a place of special interest at Wasson Bluff: "Opposite the Two Islands, the fissures of the trap are lined with fine crystals of analcime and natrolite; and the fissures and vacant spaces of the trap conglomerate in the same neighbourhood contain a reddish variety of chabasie [chabasite] in rhombohedrons, often of large size" (Dawson 1855, p.
Thomsonite varies in habit showing bladed crystals, spherulites, radial crystal groups and rich coatings mainly made up of small crystals, although it sometimes has a fibrous nature Analcime appears as vitreous and granular well-formed trapezohedral crystals which are often colourless and sometimes white Natrolite is generally beige to white, either massive or forming radiating fibers and shows a more glassy brightness than mesolite, which is generally milky white and fibrous, having larger fibers than those of natrolite Stilbite commonly occurs as vitreous sheaves or plates, ranging from colourless to green to white
Researchers report that applying crushing pressure to the mineral natrolite, one of the aluminosilicate minerals called zeolites, causes nanopores to open up and allow in--and trap--europium ions, which could lead to a new method of processing nuclear waste.

It was named by the Southern Pacific Railroad for the mineral Natrolite found in that area.
* Zeolite minerals--These include clinoptilolite-heulandite, mordinite, stilbite, laumonotite, and natrolite, at densities between 14% and 85%, with reserves estimated at more than 75 million cubic metres across Yemen, at Al-Adnah, Al Barh (Ta'iz), Al Qa'idah, Al Qubbah (Ibb), Maryah, Al-Jobah, Jabal-Hadad, Al-Hada, and Al Kawlah (Dhamar).
Short mineralogical notes on natrolite, thomsonite, phillipsite, gismondine and analcime assemblages were presented by Muhlstein and Fengl (1977), gmelinite by Barta and Rychly (1979) and Rychly et al.
