What Is Compaction And Cementation

Compaction and cementation. compaction is the process in which sediment is squeezed and in which the size of the pore space between sediment grains is reduced by the weight and pressure of overlying layers. cementation is the process in which sediments are glued together by minerals that are deposited by water.

What Is Compaction And Cementation

The main difference between the two processes is that compaction brings the sediments together, and cementation binds the sediment grains together. cementation fills the open pores with various minerals such as calcite, clay, silica and iron oxides. these minerals bind the grains together to form solid rock formations.
