WebA 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).
WebCombined Processes. As pointed out previously, if any of these process are possible, then a combination of the process could act to produce chemical change in magmas.
