What is the sequence of events in the lithification of a sandstone?

Answer 1

sand is usually well compacted during deposition, and resists additional compaction during burial. grain-to-grain contact in sand form a supporting framework that helps maintain open spaces between grains.
Lithification is a diagenetic process in which loose sediment is converted to hard rocky compaction and cementation.

So sediments (sand) are buried the increase in pressure from the weight of the overlaying material pushes the grains closer together. The volume of sediment is reduced and the fluids between the grains are also squeezed out. This leaves the sandstone tightly compressed together this is lithification.

Answer 2

In the lithification of a sandstone, the process typically starts with the deposition of sand grains, which are then compacted together by the weight of overlying sediment layers. With time, the spaces between the grains are filled with mineral cement, usually silica or calcite, binding the grains together and forming a solid rock. This cementation process creates a coherent structure and transforms the loose sand into a hard sandstone rock.
