4 Crystals and Crystallization – Mineralogy

For example, the blue-gray barite (BaSO 4) crystals seen in this photo are tabular and have a long, an intermediate, and a short dimension. The shape, termed orthorhombic, is similar to the shape of a shoebox. Barite is an anisotropic mineral. The crystals have lots of symmetry, but it is different from the symmetry of fluorite.

Quartz – Geology is the Way

Quartz is a framework silicate and one of the naturally occurring polymorphs of SiO 2. There are two forms of quartz: α-quartz, stable below 573 °C at ambient pressure, and β-quartz, stable from 573 to 870 °C. β-quartz has an hexagonal crystal lattice with 'rings' of 6 SiO 4 tetrahedrons linked to each other.
