Bowen's sequence
The Bowen reaction series is a geological concept that describes the order in which minerals crystallize from cooling magma.
Metamorphic Facies
metamorphic facies are specific mineral assemblages in metamorphic rocks that form under similar pressure and temperature (P-T) conditions.
Main igneous rock composition
Classification chart of igneous rocks based on the mineral content. The top part is a graphical comparison of silica content and mineral content for both extrusive and igneous rocks. The bottom two rows compare rocks with the same mineral composition, but different names based on whether they formed intrusively or extrusively.
