Importance of dating methods in archeology
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. The style of the artefact and its archaeology location stratigraphically are required to arrive at a relative date. For example, if an artefact, say an oil lamp, is found co-located on the same floor of a governor's dwelling, and that floor can be dated in archaeology terms by reason of the patterns employed in the mosaic, then it is assumed that in relation to the floor that the lamp is of the same age.
Stratigraphy As A Dating Technique The underlying principle of stratigraphic analysis in archaeology is that of superposition. This term means that older artefacts are usually found below younger items. When an archaeological site is excavated the sides of the unexcavated baulk reveals layering of subsequent settlements and activity.
Stratigraphic excavation is the recording and study of these different strata as they are removed from the area. Style Analysis As An Archaeology Dating Technique The shape and style of an artefact changes through time although its function may remain the same. The changing styles of pottery, glass, stoneware, and metal objects provide archaeology analysts with known progressive sequences.
Once an artefact is compared to its known development date then whenever that item reappears in the archaeological record, of that or any other site, it can quickly be dated. The Weakness of Relative Dating The potential flaws in relative dating in archaeology are obvious.
Simply assuming that an artefact is older because it was found at a lower depth in the record is only subjective science. There are many instances of deep holes being dug for rubbish pits or to locate well water that protrude into the record of older strata injecting more modern material as they are filled in over time.
Landslides and slips can completely change the topography of an entire archaeology site burying what was once on top by that which is much older, hence reversing the strata layers. Absolute Dating As An Archaeology Dating Technique A more precise and accurate archaeology dating system is known as absolute dating and can in most circumstances provide a calendar year to the object. Since there has been a transformation in the dating techniques of archaeologists.
Absolute dating is highly dependant on laboratory analysis. There are a number of techniques that have come to archaeology through the nuclear research efforts during WW2. Radiocarbon Dating In Archaeology Radiocarbon dating uses the biological assumption that all living things absorb carbon, both ordinary carbon, C12, and radioactive carbon, C14, into their living tissue. At the moment of death the C14 begins to decay at a rate that scientists already know from other experiments.
The missing amount can then determine how long it took to be lost and therefore date the object to a precise period. C14 Radiocarbon dating can only be used on organic matter. Rocks, when formed by volcanic reaction or other cataclysmic event, contain a minute quantity of radioactive substance.
From the day of the rock's creation this radioactivity begins to deplete. Like C14, by measuring the loss, a scientist can attribute an age according to known loss rates. Luminescence Dating In Archaeology Artefacts that are made from crystalline materials and uncovered in an excavation can be dated using luminescence analysis. Crystalline minerals when subjected to intense heat will burn with differing colours of flame. Mostly used to date pottery in archaeology the method is very effective but costly.
The greatest problem with dating an artefact from an archaeology site is that nearly every absolute dating process requires the destruction of at least a piece of the object in conducting the analysis. There are relatively few dating laboratories and having an artefact dated can be an expensive exercise especially if the artefact is not of great value itself. Dating Techniques In Archaeology.

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.

Principles of Prehistoric Archaeology. Chronology: Relative and Absolute Dating methods
The emergence of man through the process of biological and cultural evolution is a story of long span of time. For the archaeologist and the prehistorian who deals with that long history of man, time is the most important consideration. The sequence of development of culture or the relationship between events that represent culture can be established only when events can be placed in proper time. Chronology, the study of events in time frame, is hence the central theme of archaeologist, like the geologist who deals with the story of earth history. In fact, chronology is one of the most fundamental issues in and perhaps a characteristic of archaeology. Archaeologists use several methods to assign ages to events of the past. They are engaged in defining the stages of hominid evolution and their artifactual record, and the assignment of a chronology to these stages.
Dating Techniques In Archaeology
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.
All the students got a good laugh at this, since to us college students this was a double entendre. Most of us already knew dating was important—to our social lives! However, the article had nothing to do with the social interaction of members of the opposite sex. No, the article, published in the March issue of The Biblical Archaeology Review , dealt with the question of whether archeology can provide precise historical chronology.
Chronology: Tools and Methods for Dating Historical and Ancient Deposits, Inclusions, and Remains
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 in which the death of a cadaver occurred. Dating methods are most commonly classified following two criteria: relative dating and absolute dating.
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.
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.

At least those in the over-thirty generation can hardly have escaped history courses where the instructor concentrated almost exclusively on chronological structure, key events and persons of the period; and the study of history boiled down to memorizing a chronological framework, the dates of kings, and dynastic charts. Does it really matter whether Columbus discovered America in , , or ?

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.
When it comes to dating archaeological samples, several timescale problems arise. The Mayan calendar used BC as their reference. More recently is the radiocarbon date of AD or before present, BP. There are two techniques for dating in archaeological sites: relative and absolute dating. Relative dating stems from the idea that something is younger or older relative to something else.
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. In the archaeology of part-literate societies, dating may be said to operate on two levels: the absolute exactness found in political history or 'history event-by-event', and the less precise or relative chronology, as found in social and economic history, where life can be seen to change with less precision over time. The contrast might also be drawn between two 'dimensions', the historical, and the archaeological, corresponding roughly to the short-term and long-term history envisaged by Fernand Braudel.
