Study Notes
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.
