WebMay 6, 2024 · The sequence in which minerals crystallize from a magma is known as the Bowen reaction series (Figure 3.3. 1 and Figure 3.3. 3 ). Of the common silicate minerals, olivine normally crystallizes first, at between 1200° and 1300°C. As the temperature drops, and assuming that some silica remains in the magma, the olivine crystals will react ... WebThe albite-anorthite system. Most of the common minerals found in igneous rocks are solid-solution phases. These include olivine, pyroxene, amphibole, biotite, and plagioclase feldspars. Crystallization behaviour is illustrated best by using the NaAlSi 3 O 8 (albite or Ab)–CaAl 2 Si 2 O 8 (anorthite or An) plagioclase system shown in Figure 4.
