Diagenesis includes various phenomena relating to formation and change of minerals, because it has a wide range of physico-chemical conditions in open to closed system. Mineralogical change in diagenesis is mainly diversified by original material, chemistry of interstitial water, sedimentary rate and geothermal gradient. Chemical differentiation and physical change are accompanied during diagenesis, which is closely related to formation of petroleum reservoirs. Usually, diagenesis is well demonstrated by vertical zoning of which the mineralogical zones are defined by assemblage of authigenic minerals.
The outline and the problems in study of diagenesis are briefly described.
