Bowen's reaction series illustrates the predictable patterns of mineral formation from cooling mag.
Option a
<h3><u>
Explanation:</u></h3>
Bowen's reaction series is broken into two branches. One is continuous series. And other is discontinuous series. Bowen's reaction series is a means of ordering common igneous silicate crystals by the heat at which they form.
Minerals at the top have a relatively large crystallization heat. This indicates that they will be the first minerals to crystallize from a magma that is cooling. IF they are chemically congruous with the magma as it continues to cool, they will grow larger by the addition of external layers of additional material.
