Twelve new chemical analyses of deep-sea phillipsite show that this zeolite is alkalic and has a Si/Al ratio of 2.44−2.79. Potassium is generally in excess of sodium. The BaO content is 0.00−0.73 weight percent. The mean index of refraction for the analyzed phillipsites is 1.477−1.486, and an increase in the index can be correlated with an increase in the BaO content and a decrease in the Na2O content. Cell parameters for the analyzed phillipsites show the following ranges: a = 9.92-10.06 Å, b = 14.11-14.20 Å. c = 14.18-14,32 Å, and V = 1,994-2,027 Å3.
