Question

Quizplus · Accepted Answer

The primary difference between phyllite and schist is the size of the mica crystals. Mica crystals within schist are larger than those within phyllite. This is because schist has undergone more intense metamorphism than phyllite, causing the mica crystals to grow larger. Additionally, both phyllite and schist contain mica, but schist may also contain other minerals such as quartz and feldspar.
