In geology, metasediment is sediment or sedimentary rock that shows evidence of having been subjected to metamorphism. The overall composition of a metasediment can be used to identify the original sedimentary rock, even where they have been subject to high-grade metamorphism and intense deformation.[1]
| Sedimentary rock | Metamorphic equivalent |
|---|---|
| Limestone | Marble |
| Mudstone | Pelite |
| Siltstone | Semi-pelite |
| Sandstone | Psammite, Quartzite |
| Conglomerate | Metaconglomerate |
