Bowen's Reaction Series


Bowen's Reaction Series :

A series of minerals formed during crystallization of a magma, in which the formation of minerals alters the composition of the remaining magma. Mafic minerals comprise a discontinuous series, in which successive minerals form at the expense of early-formed ones. The plagioclase feldspars form in a continuous series, in which the composition of plagioclase becomes progressively sodium rich, but the crystal structure of the mineral does not change
