| This calcite typically overgrows quartz and crystallizes before heulandite, stilbite, and apophyllite. |
| For example, Zeolite was dominated by heulandite, with lesser amounts of quartz and smectite. |
| Here, spectacularly large groups of scolecite, heulandite, apophyllite, and associated minerals occurred in cavities in flood basalt. |
| These include Nova Scotia's provincial mineral stilbite, as well as heulandite, analcime, chabazite, gmelinite, natrolite and thomsonite. |
| Comparison is made with assemblages at Arlington Quarry on North Mountain, where the dominant zeolite minerals are heulandite and stilbite. |
| Isomorphous with heulandite is the strontium and barium zeolite brewsterite, named after Sir David Brewster. |
