...S. Merlino; P. Orlandi Abstract A new mineral, liottite, was found in Pitigliano (Tuscany, Italy). It occurs, as flattened hexagonal prisms up to 1 cm in diameter, inside cavities of ejected blocks in a pumice deposit. The space group is P 6 m 2; a = 12.842, c = 16.091 Å. Optical data ω = 1.530, ϵ...

the “liottite” cage among the SO 4 groups (two ordered and one disordered tetrahedra). Sodalite-type cages may contain highly disordered SO 4 groups (light-grey large spheres in column I) or Cl atoms (mediumgrey small spheres in column II). Cancrinite-type cages contain H 2 O groups (black large spheres).
