Lithocorrelation: correlates units on basis of similar lithology and stratigraphic position b. Biocorrelation: similarity established on basis of fossil content and stratigraphic position WebA formation is a unit of stratigraphy. It refers to a set of sedimentary layers which are somehow distinct from those above and below them in the stratigraphic sequence. This may be because they have a different lithology, different sedimentary structures, or different fossil assemblages, or something else entirely.
