Bowen's Reaction Series

Olivine and calcium-rich plagioclase (Ca-rich plag) crystallize first in a magma chamber.
Potassium feldspar (k-spar), muscovite, and quartz crystallize last in a magma chamber.
Rocks with pyroxene, amphibole, and plagioclase are basaltic in composition (basalt or gabbro).
Ultramafic rocks, such as peridotite, are characterized by the presence of olivine and calcium-rich plagioclase.
Rocks containing biotite and sodium-rich plagioclase (Na-rich plag) are andesitic in composition (andesite or diorite).
Granitic rocks, such as granite or rhyolite, comprise k-spar, muscovite, and quartz.
Olivine and quartz will not be found in the same rock due to different crystallization temperatures and locations.
Crystal settling is the process where crystallized minerals sink to the bottom of the magma chamber.
Granite forms at the top of magma chambers due to its lighter composition.
Peridotite occurs at the bottom of the magma chamber, where high-density minerals accumulate.
Pikes Peak is classified as a batholith, a large mass of igneous rock.
Pikes Peak is identified as non-volcanic because it is composed of granite, an intrusive igneous rock.
Rhyolite shares the same mineralogical composition as granite, reflecting similar formation conditions.
Diorite has the same mineralogical composition as andesite, indicating parallel formation environments.
Basalt is mineralogically equivalent to gabbro, representing a relationship between magma type and cooling rate.
