PPT Archeological Dating Methods

The title of this chapter could refer to several different things: for example, the use of economic theory in archaeological research or the different grounds and sources for financing archaeology in different times and political settings, both interesting and valid topics for study. The focus will be on the medieval period but outlooks will be made to other times and areas where there are illustrative examples and to general issues of theory and method. The connection between archaeology and coins, money and numismatics, has been repeatedly debated over recent decades. It was the focus of several publications, some of which should be mentioned at the start of this chapter in order to introduce the field. Importantly, Lloyd R. In , John Casey and Richard Reece brought together a group of scholars to discuss the relationship among numismatics, coins, and archaeology, resulting in the volume Coins and the Archaeologist , 2 which they later revised for a second edition. Most recent and with a slightly different direction, but equally important, is the conference proceedings volume The Archaeology of Money , 9 and the edited collection Divina Moneta 10 puts many of the ideas to work for a discussion of materiality and ritual pertaining to coins. It is perhaps telling that most of these efforts came about as conferences, aiming to discuss and investigate ways forward.

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.

Compositional analysis in archaeology involves the analysis and interpretation of chemical fingerprints obtained from archaeological materials. The evidence has application to questions about human behavior, provenance, technology, and artifact authentication. Because compositional data are inherently multivariate, a familiarity with the methods from multivariate statistics is essential.

This article presents an overview of the history of compositional anlaysis and the analytical methods employed. The main multivariate procedures used for data interpretation and presentation of results are also described. Finally, before selecting an analytical method and laboratory to perform the analysis on archaeological specimens, the article recommends obtaining answers to a list of questions.

Dendrochronology: What Tree Rings Tell Us About Past and Present

Statistical time-series analysis has the potential to improve our understanding of human-environment interaction in deep time. However, radiocarbon dating—the most common chronometric technique in archaeological and palaeoenvironmental research—creates challenges for established statistical methods. The methods assume that observations in a time-series are precisely dated, but this assumption is often violated when calibrated radiocarbon dates are used because they usually have highly irregular uncertainties.

As a result, it is unclear whether the methods can be reliably used on radiocarbon-dated time-series.

AMS dating is relatively expensive (about $/sample or more depending on prep. and archaeologists who have access to other dating methods.

Rachel Wood does not work for, consult, own shares in or receive funding from any company or organisation that would benefit from this article, and has disclosed no relevant affiliations beyond their academic appointment. Radiocarbon dating has transformed our understanding of the past 50, years. Professor Willard Libby produced the first radiocarbon dates in and was later awarded the Nobel Prize for his efforts. Radiocarbon dating works by comparing the three different isotopes of carbon. Isotopes of a particular element have the same number of protons in their nucleus, but different numbers of neutrons.

This means that although they are very similar chemically, they have different masses. The total mass of the isotope is indicated by the numerical superscript. While the lighter isotopes 12 C and 13 C are stable, the heaviest isotope 14 C radiocarbon is radioactive. This means its nucleus is so large that it is unstable. Over time 14 C decays to nitrogen 14 N. Most 14 C is produced in the upper atmosphere where neutrons, which are produced by cosmic rays , react with 14 N atoms. This CO 2 is used in photosynthesis by plants, and from here is passed through the food chain see figure 1, below.

Every plant and animal in this chain including us! When living things die, tissue is no longer being replaced and the radioactive decay of 14 C becomes apparent.

Radiometric dating methods. The general principle of isotope dating methods is based on the presence of radioactive isotopes in the geologic or archaeological object to be dated. The decay with time of these isotopes is used to determine the ‘zero’ time corresponding to the event to be dated.

In geology, rock or superficial deposits, fossils and lithology can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating which provided a means of absolute dating in the early 20th century, archaeologists and geologists used this technique to determine ages of materials.

Dating in Archaeology

What is Archaeology? The study of the human past through material evidence of humansthe archaeological record. Archaeologists attempt to reconstruct and interpret the cultural change and variation of the human past. Objects alone do not help us much When things are found in context, in their original setting, we gain a much more information. Context, means where an artifact is found.

Part 1 – Archaeology Methods & Techniques. Includes dating techniques (both absolute and relative methods), stratigraphy and archaeological method.

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.

Dendrochronology is the study of data from tree ring growth. Due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines. There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited. Most people who enter into studying tree rings typically come from one of several disciplines:.

Though dendrochronology also has uses for art historians, medieval studies graduates, classicists, ancient and historians due to the necessity to date some of the materials that the fields will be handling in their research projects. Typically, a bachelor’s degree in any of the above disciplines are enough to study the data that comes out of dendrochronology.

Trees are a ubiquitous form of plant life on planet Earth. They are the lungs of the world, breathing in carbon dioxide and breathing out the oxygen on which animal life depends. They live in all sorts of conditions too: in temperate and tropical areas and in arid locations, from mountain landscapes to the rainforests of the equator and the temperate uplands of Scandinavia, they are everywhere. They are used for decoration in parks and gardens all over the world.

They come in all shapes and sizes from the smallest saplings up to the colossal redwoods of North America – it could be said that we take them for granted, yet they are vital to teaching us about many aspects of our past. Trees evolved around million years ago 2.
