Metasedimentary rock
In geology, metasedimentary rock is a type of metamorphic rock. Such a rock was first formed through the deposition and solidification of sediment. Then, the rock was buried underneath subsequent rock and was subjected to high pressures and temperatures, causing the rock to recrystallize. The overall composition of a metasedimentary rock can be used to identify the original sedimentary rock, even where they have been subject to high-grade metamorphism and intense deformation.[1]
Types of metasedimentary rocks
| Sedimentary rock | Metamorphic equivalent |
|---|---|
| Pure Limestone | Marble[2] |
| Impure (Silica or clay-rich) Limestone | Calc–silicate rock[2] |
| Mudstone | Pelite |
| Siltstone | Semi-pelite |
| Sandstone | Psammite, Quartzite[2] |
| Conglomerate | Metaconglomerate |
| Shale | Slate |

gollark: There are others?!
gollark: Which is probably slower and harder than just factoring the primes.

gollark: You are aware that ANY prime from it can be factored in less than a second with unoptimized code on my low end desktop?
