In the discontinuous series of Bowen's reaction series,the first mineral to crystallize from a mafic melt is

C) pyroxene.
D) quartz.

Question

Quizplus · Accepted Answer

In Bowen's reaction series, olivine is the first mineral to crystallize from a mafic melt because it has the highest melting temperature compared to other minerals in the series. As the melt cools, olivine crystals form and are removed from the melt, causing the composition of the remaining melt to change, leading to the crystallization of other minerals in the series.
