Question

Quizplus · Accepted Answer

Minerals with the lowest melting point are the first to melt as rock is heated. This is called the principle of partial melting, where different minerals in a rock melt at different temperatures depending on their chemical composition. The minerals that have the lowest melting point are typically the mafic minerals, such as olivine and pyroxene, which are found in basaltic rocks.
