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.
Epistilbite is not easy to identify in hand specimen and most of the epistilbite identifications are from XRD and electron microprobe chemical analyses.
In contrast, on the North Shore, all epistilbite, thomsonite, and mesolite analyses lie in this field, together with wairakite and many chabazite analyses, two minerals not analyzed from Kings County.
The zeolite minerals identified on the North Shore of the Minas Basin include "heulandite", chabazite, gmelinite, analcime, wairakite, stilbite, barrerite, natrolite, scolecite, mesolite, thomsonite, laumontite, stellerite, tetranatrolite, and epistilbite.
