hydrated barium aluminosilicate mineral, (Ba,Na,K)1-2 (Si,Al)8O16 6H2O, in the zeolite family. Harmotome is isostructural with the mineral phillipsite; that is, the three-dimensional structure of the aluminosilicate framework is the same in the two substances. Its glassy, crosslike twinned crystals vary in colour from white to gray, yellow, red, and brown. It is ordinarily found with chabazite in basalts, as in Bodenmais, Germany; Kongsberg, Norway; and western Scotland. For detailed physical properties, see zeolite (table)
