The processes by which sediments are changed into rock are complex, but can be simplified into two processes, called compaction and cementation.
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.
