crystallization Maksud & Definisi

Contoh crystallization

• The intra-suite elemental variations can be best explained by fractional crystallization for reasons presented below.

• Crustally-contaminated andesites could be produced by combined assimilation and fractional crystallization of basaltic magmas.

• Crystallization proceeded to approximately the same stage in all orbicules, when the felsic shell started to form.

• During crystallization of the orbicules, no mechanical transport of crystals out of the system can be proved.

• The presence of quartz-filled microcracks in feldspar crystals suggests that deformation continued during cooling and crystallization.

• Since the subsequent crystallization to form the orbicules only took place around discrete cores, all other pre-existing nuclei must have been removed.

• In other cases parts of the structure (loops or domains) are removed during cloning to facilitate crystallization.

• These glasses were formed respectively by over 75 % and 97 % fractional crystallization of basaltic liquid at low pressure.
