Archaeological Dating: Stratigraphy and Seriation
Archaeologists dating many different techniques to determine the age of a particular artifact, site, or part archaeological a site. Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy meaning based on the law of superposition–like a article source cake, the lowest layers must have been formed first. In other words, artifacts found in the upper layers of a seriation will have been deposited more recently than those found in the lower layers. Cross-dating of sites, comparing geologic strata at one site with meaning location and extrapolating the relative ages in that manner, meaning seriation an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.
Dating techniques are procedures used by scientists to determine the age of rocks, fossils, or artifacts. Relative dating methods tell only if one sample is older or younger than another; absolute dating methods provide an approximate date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element decays into a non-radioactive product at a regular rate.
Thermoluminescence dating measures how many years have elapsed since the heating of a material containing a crystalline mineral.

For those researchers working in the field of human history, the chronology of events remains a major element of reflection. Archaeologists have access to various techniques for dating archaeological sites or the objects found on those sites.
There are two main categories of dating methods in archaeology : indirect or relative dating and absolute dating. Relative dating includes methods that rely on the analysis of comparative data or the context eg, geological, regional, cultural in which the object one wishes to date is found. This approach helps to order events chronologically but it does not provide the absolute age of an object expressed in years.
Relative dating includes different techniques, but the most commonly used are soil stratigraphy analysis and typology. On the other hand, absolute dating includes all methods that provide figures about the real estimated age of archaeological objects or occupations. These methods usually analyze physicochemical transformation phenomena whose rate are known or can be estimated relatively well. This is the only type of techniques that can help clarifying the actual age of an object.
Absolute dating methods mainly include radiocarbon dating, dendrochronology and thermoluminescence. Stratigraphy Inspired by geology , stratigraphy uses the principle of the superposition of strata which suggests that, in a succession of undisturbed SOILS , the upper horizons are newer than the lower ones.
The production of phase interpretations is the first goal of stratigraphic interpretation and excavation. Archaeologists investigating a site may wish to date the activity rather than artifacts on site by dating the individual contexts which represents events. Some degree of dating objects by their position in the sequence can be made with known datable elements of the archaeological record or other assumed datable contexts deduced by a regressive form of relative dating which in turn can fix events represented by contexts to some range in time.
For example, the date of formation of a context which is totally sealed between two datable layers will fall between the dates of the two layers sealing it. However the date of contexts often fall in a range of possibilities so using them to date others is not a straightforward process. Take the hypothetical section fig A.
seriation definition: Noun (plural seriations) 1. the arrangement of things in a series 2. the relative dating of archaeological artifacts in a chronological order.
Toggle nav. 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.
Seriation is a standard method of dating in archaeology. It can be used to date stone tools, pottery fragments, and other artifacts. In Europe, it has been used frequently to reconstruct the chronological sequence of graves in a cemetery e. Seriation “invokes the idea that any investigator, in order to assign some plausible meaning to a given phenomenon, must interpret it within a series of comparable phenomena. Art historian Erwin Panofsky has explained the situation in very clear terms:.

An Introduction to Seriation
O’Brien and R. The authors offer a critical review and explanation of each method, along with a useful historical background of each. This background is crucial for the understanding of why we proceed the way we do in archaeological practice today, and for understanding where some things might have gone ‘wrong’ or gotten confused.
Seriation can be used to date just about anything! Sir William Flinders Petrie, who had assemblages from various Predynastic Egyptian cemeteries, first implemented this dating method. Sir Petrie. Objects evolve over time based both on style and function, and these changes can be organized and tracked to form relative dating chronologies over various archaeological sites to get a better understanding of the development and spread. It is also worth noting that different types of artifact change in style decoration and shape at different rates, and therefore vary in the chronological distinctions that they indicate.
Like goes with like. When something is produced around the same time as something else, they usually look pretty similar. As styles change and develop, they gain more popularity and become more widely used. Then as a newer style or function comes into play, the older one starts to wane out. This pattern creates what we call a battleship curve, and this is the shape we look for when trying to configure our seriation sequence.

This relative dating method, based on shared typological features, enabled Sir Flinders Petrie to establish the temporal order of a large number of Egyptian graves. It is based on the idea that an artifact type first steadily grows in popularity and then steadily declines. The technique shows how these items have changed over time and it is a way to establish chronology. Archaeological material, such as assemblages of pottery or the grave goods 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. Once the variations in a particular object have been classified by typology, it can often be shown that they fall into a developmental series, sometimes in a single line, sometimes in branching lines more as in a family tree.
