A model that illustrates the predictable patterns of mineral formation from cooling mag?

a. Bowen's reaction series

c. layered intrusion formation

b. crystal separation

d. mineral composition

Bowen's reaction series illustrates the predictable patterns of mineral formation from cooling mag.

Option a

Explanation:

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.
