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.

Absolute dating methods mainly include radiocarbon dating, dendrochronology and thermoluminescence. Stratigraphy Inspired by geology , stratigraphy uses the principle of the superposition of strata which suggests that, in a succession of undisturbed SOILS , the upper horizons are newer than the lower ones. Generally, each stratum is isolated in a separate chronological unit that incorporates artifacts. However, this method is sometimes limited because the reoccupation of an area may require excavation to establish the foundation of a building, for instance, that goes through older layers.

Dating in Archaeology

Chronometric dating has revolutionized archaeology by allowing highly accurate dating of historic artifacts and materials with a range of scientific techniques. Chronometric dating, also known as chronometry or absolute dating, is any archaeological dating method that gives a result in calendar years before the present time. Archaeologists and scientists use absolute dating methods on samples ranging from prehistoric fossils to artifacts from relatively recent history.

Types of Dating · There are mainly two types of dating; i) relative and ii) absolute or chronometric dating. · Relative dating fixes a time frame in relation to other strata.

Since its development by Willard Libby in the s, radiocarbon 14C dating has become one of the most essential tools in archaeology. Radiocarbon dating was the first chronometric technique widely available to archaeologists and was especially useful because it allowed researchers to directly date the panoply of organic remains often found in archaeological sites including artifacts made from bone, shell, wood, and other carbon based materials. In contrast to relative dating techniques whereby artifacts were simply designated as “older” or “younger” than other cultural remains based on the presence of fossils or stratigraphic position, 14C dating provided an easy and increasingly accessible way for archaeologists to construct chronologies of human behavior and examine temporal changes through time at a finer scale than what had previously been possible.

The application of Accelerator Mass Spectrometry AMS for radiocarbon dating in the late s was also a major achievement. Compared to conventional radiocarbon techniques such as Libby’s solid carbon counting, the gas counting method popular in the mids, or liquid scintillation LS counting, AMS permitted the dating of much smaller sized samples with even greater precision. Regardless of the particular 14C technique used, the value of this tool for archaeology has clearly been appreciated.

Desmond Clark observed that without radiocarbon dating “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation. However, as with any dating technique there are limits to the kinds of things that can be satisfactorily dated, levels of precision and accuracy, age range constraints, and different levels of susceptibility to contamination. Probably the most important factor to consider when using radiocarbon dating is if external factors, whether through artificial contamination, animal disturbance, or human negligence, contributed to any errors in the determinations.

For example, rootlet intrusion, soil type e.

Start studying absolute dating see how to know the terms chronometric or other There are two main types of determining an age of absolute dating, and lead.

Other radiometric dating techniques are available for earlier periods. One of the most widely used is potassium—argon dating K—Ar dating. Potassium is a radioactive isotope of potassium that decays into argon. The half-life of potassium and 1. Potassium is common in dating and minerals, allowing many samples of geochronological or archeological pottery to be dated.

Argon , a noble gas, is not commonly incorporated into such samples except when produced in dating through radioactive decay. The date measured reveals the last time that the object was chronometric chronology the closure temperature at which the trapped argon can escape the lattice. K—Ar dating dating used to calibrate the pottery polarity time scale. Thermoluminescence testing also dates items to the last time they were heated.

This technique is chronometric on the principle that all objects absorb radiation from the environment. This process frees electrons within minerals that remain caught within the item. Heating an item to degrees Celsius or higher releases the trapped electrons , producing light. This light can be measured to determine the last time the item was heated. Radiation levels do chronology remain constant over time.

Definition of absolute dating

Most of the chronometric dating methods in use today are radiometric. That is to say, they are based on knowledge of the rate at which certain radioactive isotopes within dating samples decay or the rate of other cumulative changes in atoms resulting from radioactivity. Isotopes are specific forms of elements.

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.

The chronometric dating evidence for all hominid fossils from Africa and the Near East that have previously been dated to ka is critically assessed using the concept of chronometric hygiene, and these dates are revised using Bayesian statistical analyses where possible. Sixteen relevant hominid sites lacking chronometric evidence are briefly discussed.

Chronometric evidence from 37 sites is assessed in detail. The dates for many hominid fossils are poorly constrained, with a number dated by comparisons of faunal assemblages-a method that does not have good chronological resolution for much of the last million years. For sites with stratigraphic sequences of dates, it is generally possible to refine the dating, but in some cases, the revised chronology is less precise than previous chronologies.

Comparisons of different types of chronometric dates demonstrates that archaeologists in the region should feel more confident in these dating methods.
