Archaeological material, such as assemblages of pottery or the deposited with burials, are arranged into chronological order.The types that comprise the assemblages to be ordered in this way must be from the same archaeological tradition, and from a single region or locality.
Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first.
technique in which artifacts or features are organized into a sequence according to changes over time in their attributes or frequency of appearance.
The technique shows how these items have changed over time and it is a way to establish chronology.
Sequence Dating, a relative dating method, allows assemblages to be arranged in a rough serial order, which is then taken to indicate time.
Sequence dating is a method of seriation developed by the Egyptologist Sir William Matthew Flinders Petrie.
