Beginning geology students are familiar with Bowen's reaction series depicting how different minerals crystallize under varying pressures and temperatures."

Bowen conducted experimental research at the Geophysical Laboratory, Carnegie Institution for Science of Washington from 1912 to 1937. He published "The Evolution of the Igneous Rocks" in 1928. This book set the stage for a geochemical and geophysical foundation for the study of rocks and minerals. This book became "the" petrology handbook.
