Analcime is a mineral belonging to the zeolite group, primarily composed of sodium and aluminum silicate. It typically forms in volcanic rocks and is often found in cavities or as a secondary mineral in altered basalt. Its chemical formula is NaAlSi2O6·H2O, indicating the presence of water in its structure. This mineral is usually colorless, white, or light-colored and has a glassy luster. Analcime is valued in geology and mineralogy for its unique properties and is sometimes used in the production of ceramics and as a natural zeolite in various industrial applications.
