Absolute and relative rock dating

Relative dating places events or rocks in their chronologic sequence or order of occurrence.

Absolute dating places events or rocks at a specific time.

Presumably if all the world’s outcrops were integrated, sediments representing all of geologic time would be available for examination.Superposition: The most basic concept used in relative dating is the law of superposition.Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it.The most useful indication of time equivalence is similar fossil content, provided of course that such remains are present.The basis for assuming that like fossils indicate contemporary formation is faunal succession.
