→Deep Burial (mesogenesis)
Compaction The load pressure caused by deeeper burial increase in the tightness of grain packing, decrease the porosity and thin of sediments. Increase pressure at the contact between grains cause the partial dissolution of grains, it produce the sutured grain. Chemical compaction decrease the porosity and increase the bed thinning. Deep burial cause decrease the sand porosity dramatically.

Chemical processes and changes increase in temperature during deep burial also increase rate of chemical reaction.
