WebTurning sediment into rock • Diagenesis includes: - Recrystallisation: development of more stable minerals from less stable ones, (common inlimestones) - Lithification:sediments are transformed into solid rock by compaction & cementation• Sediment is unconsolidated – grains are separate (unattached) from one another. WebThis is a repetitive process that eventually build up layers to make up a Sedimentary rock. Approximately 40 major sedimentary rock layers exposed in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old.
