Sandstone depositional environment
The depositional environment and facies succession of shallow-marine sandstone may preserve indicators of change in sea-level during transgression and regression and are often easily identified, because of the unique conditions required to deposit the different facies successions (parasequences) .Lineages differ from each other in proportion of sandstone, channel depth and the structure of upward coarsening units: lineage 1 represents alluvium formed in a river system which produced texturally mature gravels and which increased in depth downstream; lineage 2 comprises sediments deposited in shallow channels which become shallower ...

As the island erodes away, only the reef will remain, forming a reef-bound seamount. Sediment found in coral reefs is typically fine-grained, mostly carbonate, and tends to deposit between the intact coral skeletons. The composition of sandstone is primarily determined by the source material and deposition environment. Most sandstones are composed of quartz, feldspar, and rock fragments, but other minerals like micas, heavy minerals, and clay minerals can also be present.
