Gmelinite-K, Chabazite-Ca, Thomsonite-Ca, Analcime
Barranco de Carrizo, La Aldea de San Nicolás, Gran Canaria, Las Palmas Province, Canary Islands, Spain
Nice example of an epitaxial overgrowth of gmelinite-K on chabazite-Ca. The epitaxies of this location are remarkable as the two zeolite phases can be easy recognized. The chabazite core of the crystal appears to be partly dissolved. The paragenesis includes small analcime and thomsonite-Ca crystals. Collected in 2012.
