Gonnardite, phillipsite and gismondine occur as euhedral to subhedral crystals in the cavities of calcareous xenolith. Thomsonite and a scolecite-like zeolite often replace nepheline crystals, and rarely fill up minute vesicles in nephelinite. The chemical analyses were made by EDS. The most Na-rich gonnardite is (Na6.61Ca1.36) ‡"7.97 [Al9.11Si10.54O40] nH2O, and the most Na-poor one is (Na5 .21Ca1.72) ‡"6.93 [A19.47Si10.47O40]¥ nH2O. Phillipsite-K and phillipsite-Ca are recognized. The former
