JLX-698Gonnardite, Chabazite-Na, Lévyne, Phillipsite

Punta del Aguila, Playa Blanca, Yaiza, Lanzarote, Las Palmas Province, Canary Islands, Spain

Field of View: 22 mm

Vug in basaltic matrix with two dull yellowish spheres of gonnardite (XRD confirmed), phacolitic chabazite-Na (left side), hexagonal, tabular levyne and some tiny phillipsite-Na. Collected in january 1977 from a rock dump, which rocks are originally most likely from the coast at the marina. The same rock also contains spheres which have been considered as phillipsite-Na until XRD results showed it is gobbinsite.
