Science definitions for diagenetic
[ dī′ə-jĕn′ĭ-sĭs ]
The process by which sediment undergoes chemical and physical changes during its lithification (conversion to rock). Compaction, leaching, cementation, and recrystallization are all forms of diagenesis. Erosion and metamorphism are not. Oil, gas, and coal form through the diagenesis of organic sedimentary matter.
