Fossils are very important for doing long distance, even global, correlation of sedimentary strata, especially if the strata contain fossils of organisms that had wide geographic ranges (p.

The formation is the basic division for identifying and correlating sedimentary strata. strata. retrogradation. William Smith. These are commonly layers of sedimentary rock separated by breaks called bedding planes. The sedimentary "bed" is the basic unit,or fundamental building block of stratigraphy (Campbell, 1967). Sedimentary strata are usually deposited in horizontal beds.

Sedimentological interpretations are placed into a stratigraphic context for detailed interpretations of changes in environments over time. Strata are layers of rock, or sometimes soil. In nature, strata come in many layers. It is a term in sedimentary and historical geology; the singular is stratum.
