Organic sedimentary rocks Coal is an example of organically formed sedimentary rocks it is formed from the remain of plants that grew in the forests or swamps the plants remains are buried in the soil after being subjected under harsh temperature and pressure they are converted to a black combustible rock known as coal which consists of 50 of carbon. The sediments differ in size. The source materials are plant and animal remains that are transformed through burial and heat and end up as coal oil and methane natural gas.
