Compaction reduces both the volume and porosity of buried sediments, whereas cementation reduces the porosity of sediments and leaves the volume unchanged.

Question

Quizplus · Accepted Answer

Compaction involves the reduction in volume and porosity of sediment as a result of the weight of overlying material. Cementation involves the filling of pore space within sediment by minerals, which reduces porosity but does not affect volume.
