The most abundant zeolite on the larger island is analcime, whereas gmelinite and chabazite are common and stilbite and natrolite are rare (I.
Chabazite and stilbite are abundant among our studied samples; "heulandite", barrerite, epistilbite, and natrolite are rare.
Stilbite is abundant and chabazite is common in the area, with minor "heulandite" and barrerite.
Stilbite is common and associated minerals are quartz and calcite.
Analcime and natrolite are abundant, mesolite and stilbite are common, and thomsonite, chabazite, laumontite, and "heulandite" are rare.
Stilbite and epistilbite show a wider range in K content than that reported by Pe-Piper (2000) from Morden.
Nine types of zeolite were identified: epistilbite, scolecite, stilbite, stellerite, heulandite (sensu stricto), clinoptilolite, mesolite, thomsonite, and rare analcime (Table 2).

Heulandite", mesolite, stilbite, thomsonite, natrolite, tetranatrolite, and epistilbite have been analysed from both the North Shore and Arlington Quarry and can therefore be compared.
Stilbite from Arlington Quarry is generally sheaf-like, vitreous, and colourless, resembling that of the North Shore.
