| The groundmass of these leucocratic segregations is heterogeneous, consisting of centimeter-scale regions dominated by nepheline, natrolite, alkali feldspar, or wollastonite. |
| Two zeolite minerals, analcime and natrolite, were identified, representing the first authenticated occurrence of these zeolites in Ontonagon County. |
| These include Nova Scotia's provincial mineral stilbite, as well as heulandite, analcime, chabazite, gmelinite, natrolite and thomsonite. |
| On one trip he opened a huge pocket of large analcime, natrolite, and apophyllite crystals at the Big Rock quarry and shared them with everyone. |
| The bed holding the upright crystals is also natrolite in confused matted masses. |
| Epistilbite, mordenite, stellerite, natrolite, scolecite, mesolite, and chabazite are relatively uncommon, and goosecreekite and yugawaralite are extraordinarily rare. |
