{{short description|Metamorphic rock from a sedimentary precursor}}
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 [[recrystallization (geology)|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.<ref>[https://books.google.com/books?id=pOPWKkxQ9AAC&dq=metamorphic+rocks+metasedimentary+vernon&pg=PA307 Vernon, R.H. & Clarke, G.L. 2008.
