Crystallography of BerylloniteHide

Crystal System:
Class (H-M):
2/m - Prismatic
Space Group:
Cell Parameters:
a = 8.178(3) Å, b = 7.818(3) Å, c = 14.114(6) Å
β = 90°
a:b:c = 1.046 : 1 : 1.805
Unit Cell V:
902.39 ų (Calculated from Unit Cell)
Crystals tabular {010} to short prismatic [010]. Crystals are frequently very complex, especially in the zones [100] and [010]. Faces in the zone [010] near {100} may be united in oscillatory combination. Crystal faces often dull or roughened, or, in some cases, delicately etched. Crystals frequently exhibit a columnar structure due to the presence of hollow canals and fluid cavities arranged parallel to [010].
On plane {101}, as both contact and penetration twins; repeated at times, or in pseudo-hexagonal stellate forms; also polysynthetic {110} and {100}.
Marked orthorhombic pseudo-symmetry.
