WebThe processes of anatexis (partial melting of pre-existing crystalline rock) and fractional crystallization typically leave geochemical fingerprints in an evolving magma body, betraying both chemical and thermal interaction with surroundings. This is especially apparent when magma and host are 5 compositionally and thermodynamically distinct. porsche macan redesign dueWebA number of processes that take place within a magma chamber can affect the types of rocks that form once magma cools and crystallizes. If the magma has a low viscosity— which is likely if the magma is mafic—the crystals that form early, such as olivine (Figure 7.11a), may slowly settle toward the bottom of the magma chamber (Figure 7.11b). irish bar atlantic cityWebThe process by which these magmas are modified is known as magmatic differentiation.
