| Species: | Stilbite-Ca |
| Formula: | NaCa4(Si27Al9)O72 · 28H2O |
| Formation: | Secondary |
| Comments: | Radial aggregates to 2 cm, in fractures in granofels with calcite and chabazite-Ca. Two specimens, one a radiating aggregate www.mindat.org/photo-946965.html the other an isolated crystal www.mindat.org/photo-946968.html were analyzed by SEM-EDS and have a calculated apfu of Na above 0.4, and so can be safely identified as stilbite-Ca rather than stellerite, which cannot be visually distinguished. |
