"Diagenesis" comprises all mineralogical, physical, and chemical changes that happen to sedimentary deposits from the time of deposition at the Earth's surface to burial at depths of about 6 - 9 km and commensurate temperatures of about 200 oC. Diagenesis is of supreme importance for human civilization. Because of the changes in porosity and permeability, diagenesis affects the ability of the rocks to carry or store groundwater (used for human consumption and irrigation in relatively shallow settings), oil and gas (commonly in deeper settings), and certain metal ores (shallow or deep settings).

“成岩作用”包括沉积矿床从在地球表面沉积到埋藏在大约6 - 9公里深处和大约200摄氏度的相应温度之间发生的所有矿物学、物理和化学变化。成岩作用对人类文明具有极其重要的意义。由于孔隙度和渗透率的变化，成岩作用影响岩石携带或储存地下水（在相对较浅的环境中用于人类消费和灌溉），石油和天然气（通常在较深的环境中）以及某些金属矿石（浅或深环境）的能力。
