Diagenesis is the physical, chemical, or biological alteration of sediments into sedimentary rock at relatively low temperatures and pressures that can result in changes to the rock's mineralogy and texture.
Diagenesis is the process by which sediments evolve after they are deposited and begin to beburied, which can include physical effects such as compaction, as well as chemicalreactions.
Diagenesis refers to all of the chemical, physical, and biological changes undergone by sedimentafter initial deposition.
