Sedimentary rocks are formed from grains of minerals and rocks, dissolved minerals and other material, such as plant matter or animal remains, which have been transported and deposited as sediment.lant material can be found as fragments in sandstones or other sedimentary rocks, and if it makes up the bulk of the rock it is termed coal.
