    Seriation sequence dating

    , in which figures in solar years (often with some necessary margin of error) can be applied to a particular event.

    Unless tied to historical records, dating by archaeological methods can only be relative -- such as stratigraphy, typology, , fluorine and nitrogen test, and radiometric assay.

    In Europe, it has been used frequently to reconstruct the chronological sequence of graves in a cemetery (e.g.

    Jørgensen 1992; Two different variants of seriation have been applied: contextual seriation and frequency seriation (Renfrew and Bahn 1996, pp. Whereas contextual seriation is based on the presence or absence of a design style, frequency seriation relies on measuring the proportional abundance or frequency of a design style.

    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.

    Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.

    Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating.

    Petrie's problem was that he had discovered several predynastic cemeteries along the Nile River in Egypt that seemed to be from the same period, but he needed a way to put them in chronological order.He assumed that the change in styles was an evolutionary one, and, if you could quantify that change, he surmised it might be used to indicate which cemeteries were older than others.Petrie's notions about Egyptology, and archaeology in general, were revolutionary.In archaeology, seriation is a relative dating method in which assemblages or artifacts from numerous sites, in the same culture, are placed in chronological order.Where absolute dating methods, such as carbon dating, cannot be applied, archaeologists have to use relative dating methods to date archaeological finds and features.
