When this highly ordered structure extends in all three dimensions, the mineral becomes a crystal. With a theory developed by physicists in the 1920s called crystal field theory, scientists can ...

More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple ...

One of the notable discoveries is scenicite, a new uranyl sulfate mineral found in Utah, USA. Scenicite has a unique orthorhombic structure characterized by chains formed from pentagonal ...

The crystal structure of bismuth is noteworthy. Unlike many metals, which crystallize in a cubic structure, bismuth forms rhombohedral crystals. This means that the crystal lattice is skewed ...

Mineralogy is the study of the chemistry, crystal structure and physical properties of the mineral constituents of rocks. Both petrological and mineralogical processes are sensitive to environmental ...

The sodalite-group minerals are a fascinating class of aluminosilicates known for their unique crystal structures and the presence of extra-framework components. These minerals, which include ...

describing and characterising mineral substances from the atomic to the geological scale. We research the diversity of natural inorganic structures - their crystal-chemistry and physical properties.
