WebMafic magma will cool and crystallize to produce the volcanic rock basalt, whereas felsic magma will crystallize to produce dacite and rhyolite. Intermediate-composition magmas will crystallize to produce the rock andesite. Because the mafic rocks are enriched in Fe and Mg, they tend to be darker colored than the felsic rock types. WebThe chemical composition of the magma determines which minerals will form and in what proportions they will occur. Therefore, identification of the minerals present in the rock is an important step in being able to correctly identify the rock.
