Metamorphic
- Anthracite - a type of coal
- Amphibolite - a metamorphic rock composed primarily of amphibole
- Blueschist - a metamorphic rock composed of sodic amphiboles with a distinct blue color
- Cataclasite - a rock formed by faulting
- Eclogite - an ultra-high grade metamorphosed basalt or gabbro; also a facies of metamorphic rocks
- Gneiss - a coarse grained metamorphic rock
- Gossan - the product of the weathering of a sulfide rock or ore body
- Granulite - a high grade metamorphic rock formed from basalt; also a facies of metamorphic rocks
- Greenschist - a mafic metamorphic rock dominated by green amphiboles
- Greenstone
- Hornfels - a metamorphic rock formed by heating by an igneous rock
- Marble - a metamorphosed limestone
- Migmatite - a high grade metamorphic rock verging upon melting into a magma
- Mylonite - a metamorphic rock formed by shearing
- Metapelite - a metamorphic rock with a protolith of clay-rich (siltstone) sedimentary rock
- Phyllite - a low grade metamorphic rock composed mostly of micaceous minerals
- Metapsammite - a metamorphic rock with a protolith of quartz-rich (sandstone) sedimentary rock
- Pseudotachylite - a glass formed by melting within a fault via friction
- Quartzite - a metamorphosed sandstone typically composed of >95% quartz
- Schist - a low to medium grade metamorphic rock
- Serpentinite - a metamorphosed ultramafic rock dominated by serpentine minerals
- Skarn - a metasomatic rock
- Slate - a low grade metamorphic rock formed from shale or silts
- Suevite - a rock formed by partial melting during a meteorite impact
- Talc carbonate - a metamorphosed ultramafic rock with talc as an essential constituent; similar to a serpentinite
