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
They were followed by acicular-fibrous zeolites such as natrolite/ gonnardite, thomsonite, mesolite and scolecite Analcime is usually a Na-rich mineral phase, but may sometimes contain appreciable K (Utada, 1970).
They were followed by acicular-fibrous natrolite and Ca-rich zeolites such as gonnardite, thomsonite, mesolite and scolecite.
They are "heulandite" (heulandite sensu stricto and clinoptilolite), chabazite, analcime, stilbite, barrerite, epistilbite, gmelinite, laumontite, natrolite, mesolite, scolecite, stellerite, tetranatrolite, thomsonite, and wairakite.
Mesolite is generally milky white and fibrous with fibres larger than those of natrolite.
Analcime and natrolite are abundant, mesolite and stilbite are common, and thomsonite, chabazite, laumontite, and "heulandite" are rare.
