The mineral part of analysed samples is composed of clays, feldspars, carbonates, analcime, natrolite, quartz and bassanite (Table 1).
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).

In accepting her award, she said, "My research involves a detailed study of how the crystal structure of the natural zeolite natrolite changes with temperature and the partial pressure of water.
Natrolite is an extremely rare zeolite at the Fanwood quarry; specimens were discovered on one occasion as jumbles of acicular crystals, no longer than 1 cm, on prehnite in a diapiric amygdule.

Those that are lower in silica, including natrolite and analcime, are sodium-rich minerals that tend to develop in areas of higher fluid flux where more sediment-derived sodium was available.
