Archaeological Dating Methods – PowerPoint PPT Presentation
When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena. Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries. Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact’s likely age. Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating.
Relative Dating In Archaeology Relative dating in archaeology presumes the age of an artefact in relation and by comparison, to other objects found in its vicinity. Limits to relative dating are that it cannot provide an accurate year or a specific date of use.
All rights reserved. Relative techniques were developed earlier in the history of archaeology as a profession and are considered less trustworthy than absolute ones. There are several different methods. In stratigraphy , archaeologists assume that sites undergo stratification over time, leaving older layers beneath newer ones. Archaeologists use that assumption, called the law of superposition, to help determine a relative chronology for the site itself.
Then, they use contextual clues and absolute dating techniques to help point to the age of the artifacts found in each layer. Learn how archaeologists dated the earliest metal body part in Europe. Objects can be grouped based on style or frequency to help determine a chronological sequence. Relative dating has its limits. For a more precise date, archaeologists turn to a growing arsenal of absolute dating techniques. Perhaps the most famous absolute dating technique, radiocarbon dating was developed during the s and relies on chemistry to determine the ages of objects.
Its inventor, Willard Libby, eventually won a Nobel Prize for his discovery.
Archaeological Dating: Stratigraphy and Seriation
Dating refers to the archaeological tool to date artefacts and sites, and to properly construct history. Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope. Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope 14 C.
This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.

The real meaning of history is to trace the developments in various fields of the human past. Towards this end, while investigating the past cultures, archaeology depends on various dating methods. These dating methods can broadly be divided into two categories, i. These are mainly non-scientific dating methods. These methods were relied on especially prior to the introduction of scientific methods of dating. But, even when the scientific methods of absolute dating are available, this method of dating has not lost its importance, as many a time we have to depend solely on relative dating.
Even when the absolute dates are available, we have to supplement the information with relative dating. The various methods of relative dating are;. This method depends on the common observation that the height of the habitational area increases as the people continue to live at the same place. The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.
Chronology and dating methods
The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place. Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. In such cases, dating might seem easy. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.

Interest in the origins of human populations and their migration routes has increased greatly in recent years. A critical aspect of tracing migration events is dating them. Inspired by the Geographic Population Structure model that can track mutations in DNA that are associated with geography, researchers have developed a new analytic method, the Time Population Structure TPS , that uses mutations to predict time in order to date the ancient DNA.
At this point, in its embryonic state, TPS has already shown that its results are very similar to those obtained with traditional radiocarbon dating. We found that the average difference between our age predictions on samples that existed up to 45, years ago, and those given by radiocarbon dating, was years. This study adds a powerful instrument to the growing toolkit of paleogeneticists that can contribute to our understanding of ancient cultures, most of which are currently known from archaeology and ancient literature,” says Dr Esposito.
Radiocarbon technology requires certain levels of radiocarbon on the skeleton, and this is not always available.

Dating methods are the means by which archaeologists establish chronology. The more dating methods we use to construct a chronology, the more likely it is that the chronology will be reliable. The most universal dating method in archaeology is a relative dating method: dating by association. At it simplest, this means recognising an artefact or structure as belonging to a known type of a particular date. Where there is a significant number of these associations, the dating information they give us becomes more reliable – individual cases can be misleading – artefacts, for instance, may be residual belonging to an earlier period but present in a later context due to redeposition.
The more associations we have, the easier it is to see such problems in the evidence, and therefore the more likely the site chronology is to be correct. Archaeologists must depend on their experience to guide them as to the most effective use of resources in commissioning scientific dating programmes. Often, this only becomes clear at the post-excavation stage.
It is always good practice therefore, to take a wide range of samples of any datable material during excavation so that there will be maximum potential for a dating programme at a subsequent stage of the work.

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. Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Stratigraphy is based on the law of superposition–like a layer cake, the lowest layers must have been formed first. In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.
Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning. The scholar most associated with the rules of stratigraphy or law of superposition is probably the geologist Charles Lyell. The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.
Seriation, on the other hand, was a stroke of genius. First used, and likely invented by archaeologist Sir William Flinders-Petrie in , seriation or sequence dating is based on the idea that artifacts change over time. Like tail fins on a Cadillac, artifact styles and characteristics change over time, coming into fashion, then fading in popularity. Generally, seriation is manipulated graphically.

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.
All dating methods have advantages and disadvantages. Sometimes we have no choice since only one method can be applied to our particular site. However.
Without the ability to date archaeological sites and specific contexts within them, archaeologists would be unable to study cultural change and continuity over time. No wonder, then, that so much effort has been devoted to developing increasingly sophisticated and precise methods for determining when events happened in the past.
Chronometric dating techniques produce a specific chronological date or date range for some event in the past. For example, the results of dendrochronology tree-ring analysis may tell us that a particular roof beam was from a tree chopped down in A. Relative dating techniques , on the other hand, provide only the relative order in which events took place. For example, the stratum, or layer, in which an artifact is found in an ancient structure may make it clear that the artifact was deposited sometime after people stopped living in the structure but before the roof collapsed.
