The term zeolite was originally coined in 1756 by Swedish mineralogist Axel Fredrik Cronstedt, who observed that upon rapidly heating the material stilbite, it produced large amounts of steam from water that had been adsorbed by the material.
Zeolites are microporous aluminosilicate minerals such as analcime, chabazite, clinoptilolite, heulandite, natrolite, phillipsite, and stilbite. Figure 4 shows the microporous molecular structure of zeolite, ZSM-5.

Zeolites derive their name from the Greek words for "boil" and "stone" because, back in the 18th century, Swedish mineralogist Axel Fredrik Cronstedt found that heating a type of naturally occurring mineral called stilbite released copious amounts of steam.

Apatite ilmenite magnetite and hematite occur as accessories and chlorite, calcite, stilbite, antigorite and clay are secondary.
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

After feverishly collecting minerals in a sea "cave, roofed and paved with stilbite" (another zeolite, Ca[Al.sub.2][Si.sub.7][O.sub.18] x 7[H.sub.2]O, which is common in amygdales and now the provincial mineral of Nova Scotia), Emmons and Hopkins emerged around noon to find that the rest of the party had completely disappeared.
* 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).
