Examples:
* Slate: Fine-grained, metamorphic rock formed from shale. Easily splits into thin layers.
* Phyllite: Fine-grained, metamorphic rock with a silky sheen. Has a slightly more pronounced foliation than slate.
* Schist: Medium to coarse-grained, metamorphic rock with visible mineral crystals and distinct foliation.
* Gneiss: Coarse-grained, metamorphic rock with alternating bands of light and dark minerals. Often has a distinct banding pattern.
* Mylonite: Metamorphic rock formed by intense shearing. Has a well-developed, often finely layered foliation.
Other examples:
* Amphibolite
* Eclogite
* Greenschist
* Serpentinite
Examples:
* Marble: Metamorphic rock formed from limestone. Usually white, but can be other colors depending on impurities.
* Quartzite: Metamorphic rock formed from sandstone. Hard, durable, and resistant to weathering.
* Hornfels: Metamorphic rock formed by contact metamorphism. Often dense and fine-grained.
* Anthracite: Metamorphic rock formed from coal. Has a high carbon content and a shiny, black appearance.
Other examples:
* Skarn
* Greenstone
* Migmatite (partially foliated, so can be considered both foliated and unfoliated)
It's important to note that some rocks can be classified as both foliated and unfoliated, depending on the specific type and degree of foliation present.
