Phyllite is a foliated, metamorphic rock that has a texture intermediate between slate and schist. It is typically composed of fine-grained mica minerals, such as muscovite or biotite, and often exhibits a glossy or waxy sheen due to the alignment of these minerals. While it is similar to slate in terms of its ability to split into thin, flat sheets, it is more strongly foliated and may also exhibit a noticeable grain or lineation.
