Dating Techniques in Archaeological Science
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.

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.
Dating Methods in Historical Archaeology
Dating methods Dating techniques are procedures used by scientists to In a landmark study, archaeologist James Ford used seriation to determine the.
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. According to this method, the upper deposits are younger and the lower deposits are older.
Basing on this principle, the cultural assemblages found in different layers can be assigned a chronological personality. For example, if the cultural contents of the lower deposit are Mauryan in character, appropriately this deposit may be assigned a date between B.
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.

Dating in Archaeology
Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people.
The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences.

Prior to the development of radiocarbon dating , it was difficult to tell when an archaeological artifact came from. Unless something was obviously attributable to a specific year — say a dated coin or known piece of artwork — then whoever discovered it had to do quite a bit of guesstimating to get a proper age for the item. The excavator might employ relative dating, using objects located stratigraphically read: buried at the same depth close to each other, or he or she might compare historical styles to see if there were similarities to a previous find.
But by using these imprecise methods, archeologists were often way off. Fortunately, Willard Libby, a scientist who would later win the Nobel Prize in Chemistry, developed the process known as radiocarbon dating in the late s. It’s still the most commonly used method today. In a nutshell, it works like this: After an organism dies, it stops absorbing carbon , so the radioactive isotope starts to decay and is not replenished. Archaeologists can then measure the amount of carbon compared to the stable isotope carbon and determine how old an item is.
For the most part, radiocarbon dating has made a huge difference for archaeologists everywhere, but the process does have a few flaws. For example, if an object touches some organic material like, say, your hand , it can test younger than it really is. Also, the larger the sample the better, although new techniques mean smaller samples can sometimes be tested more effectively. The data can be a little off particularly in younger artifacts, and anything older than about 50, years is pretty much too old to be tested because at that point the majority of the C has decayed to practically undetectable levels.

Archaeology: the study of the material remains of people from the past. Dating methods here overlap with those discussed in anthropology, but archaeologists are.
Having an accurate time scale is a crucial aspect of reconstructing how anatomical and behavioral characteristics of early hominids evolved. Relative dating methods allow one to determine if an object is earlier than, later than, or contemporary with some other object. It does not, however, allow one to independently assign an accurate estimation of the age of an object as expressed in years.
The most common relative dating method is stratigraphy. Other methods include fluorine dating, nitrogen dating, association with bones of extinct fauna, association with certain pollen profiles, association with geological features such as beaches, terraces and river meanders, and the establishment of cultural seriations. Cultural seriations are based on typologies, in which artifacts that are numerous across a wide variety of sites and over time, like pottery or stone tools.
If archaeologists know how pottery styles, glazes, and techniques have changed over time they can date sites based on the ratio of different kinds of pottery. This also works with stone tools which are found abundantly at different sites and across long periods of time.

It is a relative dating technique which compares concentrations of fluorine, uranium, or nitrogen in various samples from the same matrix to determine contemporaneity. Its range is , years to 1. The date on a coin is an absolute date, as are AD or BC. It is used for human and animal bone and other organic material.
Archaeologists use many different techniques to determine the age of a of the relative dating methods that archaeologists use to date things.
The African archaeological record is particularly remarkable in that it covers timescales relevant to all human history and prehistory. Different dating techniques are therefore fundamental to constructing reliable chronologies for the continent. The principal factors that determine the usefulness of a dating technique are 1 applicability to the material in question, 2 the expected precision of the technique, and 3 the age range over which it is expected to be useful.
Radiocarbon is applicable to the past fifty thousand years of human history, encompassing the Later Stone Age, Iron Age, and historical periods, and is a highly-refined method applicable to organic materials such as bones, plant matter, charcoal, teeth, and sometimes eggshell. However, African archaeological contexts often present challenges to the preservation of material, and it is important to establish the context of the material under investigation.
Materials of preference for radiocarbon dating, such as plant cellulose, are thought to be resistant to alteration during burial diagenesis. The age ranges of luminescence and uranium-series dating stretch well into the African Middle Stone Age. Luminescence dating is applied to sediments and burnt objects, and uranium-series U-series dating is applied to geological materials such as carbonates and stalagmites.
In some special cases, U-series dating can also be applied to fossil bones, teeth, and eggshell. For all dating methods the importance of context cannot be overstated. Other techniques, such as archaeomagnetic dating and rehydroxylation RHX dating, should be applicable over the historical period, but these new methods are under development. Dating methods are an active area of interdisciplinary research, continuously refined and developed, and collaboration between African archaeologists, geologists, and dating specialists is important to establish accurate regional chronologies.
