6.1: Clastic Sedimentary Rocks
Lithification is the term used to describe a number of different processes that take place within a deposit of sediment to turn it into solid rock (Figure (PageIndex{5})). One of these processes is burial by other sediments, which leads to compaction of the material and removal of some of the intervening water and air.
