| Species: | Hydroxyapophyllite-(K) |
| Formula: | KCa4(Si8O20)(OH,F) · 8H2O |
| Comments: | Occurs sparingly in prehnite veins as white cubic crystals with minor pyramidal modifications, to 3mm. Also occurs as coatings of similar crystals in open veins without other minerals. The best from this location occurred as pink prisms with pyramidal terminations, associated with muscovite, plagioclase, chlorite, and calcite. These were found in the same alteration zone as the one-time kainosite-Y find. |
