These aggregates of hexagonal gmelinite crystals are a classic of Northern Ireland mineralogy. In this specimen we can enjoy a vacuole covered by orange crystals, very well defined and brilliant. They are accompanied by small analcime crystals, richly faceted and transparent. Gmelinite specimens from this quarry were analyzed by X-ray fluorescence and SEM-EDS by Stephen Moreton. The results indicated that both gmelinite-Ca and gmelinite-Na are present and even zoned in the same crystal.

Very curious specimen of hydroxylapophyllite-(K) formed by numerous crystals inside a geode resembling a nodule. They are accompanied by small needles of calcite very fluorescent (bluish).
