Question

Quizplus · Accepted Answer

The last minerals to crystallize from a cooling magma are the ones with the lowest melting point and the highest percentage of silica. This is because these minerals require the highest amount of heat to melt and have a high amount of silica, which increases their melting point. Therefore, they are the last to crystallize as the magma cools and solidifies.
