Theories of Crystal Growth
The transition from the ‘nucleus’ phase to the ‘crsytal’ phase is performed through a progressive addition of atoms or molecules at the surface of the nucleus. In a system where liquid → solid transformations are produced, nuclei that have not been absorbed grow faster if the energy level is raised to the high temperatures or if the surrounding solution is oversaturated. In systems with solild → solid transformations, processes of crystal growth are more complicated. As in heterogenous nucleation, they depend on several variables which also define the size and morphology of the newly formed minerals (blast).
