The Bowen Reaction Series

In 1922, Norman Levi Bowen and his colleagues determined the sequence in which silicate minerals crystallize as magma cools (Chernicoff 56). This work made it possible to summarize a complex set of geochemical relationships, called Bowen's Reaction Series.
This series shows that silicate mineralscancrystallize from mafic magmas in two ways, in a discontinuous series or a continuous series.
