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.
Relative dating and absolute dating in archaeology
Dating methods in archaeology establish the time and sequence of events that created archaeological deposits and layers, called strata, within those deposits. Dating methods are either absolute or relative. Examples of each method, respectively, are dendrochronology, carbon, archaeomagnetism, and the known year a city was destroyed. Relative dating is based on stratigraphy the tendency of younger layers to lie over older layers and comparison of artifacts from undated sites to sites where dates are established.
Archaeological dating has undergone rapid development as part of a more general trend samples for several different dating methods. At Kaminaljuyu, for.
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.

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.

Dating in archaeology is the process of assigning a chronological value to an event in the past. Philosophers differ on how an event is defined, but for cultural history, it can be taken as a change in some entity: the addition, subtraction, or transformation of parts. Events can be considered at two scales. At the scale of individual object, the event is either manufacture which, e.
At the scale of more than one object, often called an assemblage, the event is usually the deposition of those objects at a single place. Such an event, if human caused, is often called an occupation.

Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred.
Other markers can help place an artifact or event in a chronology, such as nearby writings and stratigraphic markers. Dating methods are most commonly classified following two criteria: relative dating and absolute dating. Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known. In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the most recent and the oldest possible moments when an event occurred or an artifact was left in a stratum , respectively.
