Stilbite is usually monoclinic 2/m, meaning that it has one twofold axis of rotational symmetry perpendicular to a mirror plane. The twofold axis is the crystal axis b, and the a and c crystal axes lie in the mirror plane. For a monoclinic crystal a and c are inclined to each other at an angle β which is not a right angle. For stilbite β is nearly 130°. Stilbite crystals, however, appear to be almost orthorhombic, and a larger unit cell can be chosen, containing two formula units (Z = 2) su… WebOct 1, 2024 · It crystallizes in the orthorhombic system (space group C 222) [ 1] but shows a strong pseudo-hexagonal symmetry around the Ca-SO 4 - chains which has led to its description in various space groups. β -anhydrite was first identified as “anhydrous sulfated lime” ( chaux sulfatée anhydre) in 1801 by R.-J.
