Hopeite crystallizes in the orthorhombic system with druzy encrustations and reniform ( kidney-shaped ) masses.
12.
Lithiophylite is a resinous reddish to yellowish brown mineral crystallizing in the orthorhombic system often as slender prisms.
13.
Topaz crystallizes in the orthorhombic system, and its crystals are mostly prismatic terminated by pyramidal and other faces.
14.
In the triclinic system, the crystal is described by vectors of unequal length, as in the orthorhombic system.
15.
Crystals of perovskite appear as cubes, but are " pseudocubic " and crystallize in the orthorhombic system.
16.
Schr�ckingerite crystallizes in the orthorhombic system, occurring as globular clusters, and fluoresces yellow-green under ultraviolet light.
17.
Epsomite crystallizes in the orthorhombic system as rarely found acicular or fibrous crystals, the normal form is as massive encrustations.
18.
Thenardite crystallizes in the orthorhombic system and often forms yellowish, reddish to gray white prismatic crystals although usually in massive crust deposits.
19.
The latter crystallizes at " 220 �C ( " 364 �F ) and is transparent and soft, with the same disordered orthorhombic systems of other solid halogens.
20.
For non-orthorhombic systems, the determination of cell parameters might be more complicated, but many ab-initio numerical packages have utilities to make this calculation simpler.
