A sedimentary rock is a classification of rock that forms from layers of sediments deposited and consolidated at the bottom of oceans, lakes, or other bodies of water. These rocks are formed from sediment such as minerals and other organic matter. See the fact file below for more information on the sedimentary rock or alternatively, you can download our 24-page Sedimentary Rocks worksheet .

Thus the sequence stratigraphic framework is used to analyze and explain how sedimentary rocks acquire their layered character, lithology, texture, faunal associations and other properties. These properties in turn can be used to explain how the mechanisms of sediment accumulation, erosion and inter-related processes produced the current configuration of these rocks.

(1) Sedimentary rocks are formed of sediments derived from the older rocks, plant and animal remains and thus these rocks contain fossils of plants and animals. The age of the formation of a given sedimen­tary rock may be determined on the basis of the analysis of the fossils to be found in that rock.
