Sedimentary rocks include all unconsolidated or consolidated natural materials deposited in an environment having some potential for preservation. Environments.Step 3: Consistency with Other Features. Compare your environmental hypothesis to the characteristics implied by other sedimentary structures in the column and evaluate whether they are consistent with your tentative environmental interpretation. Examples of other sedimentary structures: Trough cross stratification.

Limestone, which is composed of calcium carbonate, forms by both chemical and biochemical means; dolostone, which is composed of calcium-magnesium carbonate, forms strictly by chemical means; chert, which is composed of microcrystalline quartz, forms most often chemically and to a lesser extent biochemically.Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.Deltaic – Silt deposition landform at the mouth of a river (possible cross beds, ripple marks)[5] Common sediments are sand, silt, and clay. ... and the sedimentary depositional environment, that lies below the everyday wave base; Deep water marine environment – Flat area on the deep ocean floor (abyssal plains) caused by ocean …The limestone deposited in the far shelf comes from CaCO 3 dissolved in the river waters during the weathering of feldspars.

In the marine environment, Demaison and Moore (1980) recognized a series of depositional settings where source rock might be deposited linked to organic matter preservation. Those ideas were further refined by Demaison et al.
