WebThe four most common types of foliated rock, in order of increasing metamorphic grade are slate, phyllite, schist, and gneiss. These four different kinds of rocks all contain different metamorphic minerals and fabrics and vary depending on their protolith compositions. We discuss each in more detail below.
