according to the geological society, compaction occurs when sediments are buried underneath other layers causing them to stick together due to pressure. on the other hand, cementation occurs when new minerals act as binding agents that bind the sediments together. the main difference between the two processes is that compaction brings the sediments together, and cementation binds the sediment grai.read more≫
