Cementation is the process of cementing minerals coating the sediment grains and gluing them together into a fused rock. Figure 5.3.1 5.3. 1: Permineralization in petrified wood. Diagenesis is an accompanying process of lithification and is a low-temperature form of rock metamorphism (see Chapter 6, Metamorphic Rock).

5.3.1 Lithification and Diagenesis. Lithification turns loose sediment grains, created by weathering and transported by erosion, into clastic sedimentary rock via three interconnected steps. Deposition happens when friction and gravity overcome the forces driving sediment transport, allowing sediment to accumulate.
