Diagenics

Diagenesis refers to the processes that occur in sediments after they are deposited, transforming them into sedimentary rock. This involves physical, chemical, and biological changes, such as compaction, cementation, and mineral alteration. Essentially, as layers of sediment build up over time, the weight of the new layers compresses the ones below, leading to hardening and changing their composition. Diagenesis is crucial in understanding geological history and resources, as it affects how rocks form, their properties, and their potential for storing oil, gas, and water.
