    www.minsocam.org/ammin/AM75/AM75_1415.pdf MONTESOMMAITE The known chemical and crystallographic data for montesommaite are consistent with new mineral be-ing a member of the zeolite family. The pseudotetragonal orthorhombic cell and the a and b lattice parameters of l0 A suggest a framework with a 4.8'? net (Smith, 1978), which occurs in merlinoite and gismondine.
