8. Identify (use a descriptive name) a sedimentary depositional environment in which a significant amount of carbon is deposited and identify the sedimentary rock that is produced. For this depositional environment, identify the form of the carbon that is deposited, whether the sedimentary process is clastic, biological or chemical, continental or marine, the tectonic- climatic factors that help create the environment, and a geographic example. Depositional environment: Sedimentary rock: Form of carbon bearing material deposited: Clastic, biological or chemical process: Continental or marine: Tectonic-climatic factors: Geographic example:Explanation / Answer
Depositional Environment: swamps on low-lying ground in deltas, alluvial plains and coastal areas
Sedimentary rock: Coal
Form of carbon bearing material deposited: Organic carbon from plant debris.
Clastic, biological or chemical process: Coal is formed mainly by chemical processes
Continental or marine: The depositional environment for coal is primarily marine.
Tectonic-climatic factors: Slowly sinking crustal movement is evident for coal formation. The suitable climate for coal formation is humid and temperate climate with high temperature and high rainfall.
Geographic example: Pittsburgh coal seam in Great Britain.
