WebDec 8, 2024 · Sequence Stratigraphy. Sequence Straigraphy is the study of rock units within a chronostratigrphic framework bounded by erosional surfaces, nondeposition, or conformities. History.

While he was a senior scientist at Exxon, he come up with three core … A sequence of fossil-bearing sedimentary rocks can be subdivided on the basis of the occurrence of particular fossil taxa. A unit defined in this way is known as a biostratigraphic unit, generally shortened to biozone. The five commonly used types of biozone are assemblage, range, abundance, interval and lineage zones. • An assemblage zone is a stratigraphic interval characterised by an assemblage of three or mor…
