Crystallography in geology
WebTemplate:Redirect2 Template:Crystallization Crystallization is the (natural or artificial) process of formation of solid crystals precipitating from a solution, melt or more rarely deposited directly from a gas. Crystallization is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid … WebCrystallography is useful in phase identification. When manufacturing or using a material, it is generally desirable to know what compounds and what phases are present in the material, as their composition, structure and proportions will influence the material's properties. Each phase has a characteristic arrangement of atoms.

WebWhen a rock or mineral is subjected to stress, stress is proportional to strain as long as the elastic limit has not been exceeded. This relationship is known as Hooke's law. Plastic deformation takes place when a rock, mineral, or other substance is stressed beyond its elastic limit ( Fig. 1 ). Plastic deformation is that deformation that ...
