Question

what is the difference between the compaction and Cementation

Answer 1

Compaction happens when sediments are deeply buried, placing them under pressure because of the weight of overlying layers. This squashes the grains together more tightly.


Cementation is where new minerals stick the grains together – just as cement (from a bag) binds sand grains in a bricklayer’s mortar. If you look carefully at the microscope photo, you can see mineral crystals that have grown around the sediment grains and bonded them together.
