Methods of absolute or chronometric dating have developed greatly over recent years, with dendrochronology and radiocarbon dating in particular being used extensively by archaeologists. While relative dating techniques such as typology and frequency seriation can be used to put objects and sites in a chronology relative to each other, we must look to other methods to provide specific calendar dates. One such method is dendrochronology, the study of tree ring growth, and was first put to notable use by A. Douglass in the ‘s. Soon after William Libby made another pivotal discovery while examining unstable carbon isotopes- radiocarbon dating. In this essay I hope to outline the actual processes involved in both methods, compare their merits and give examples of their use in dating sites.

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.

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.
However, the stratigraphic position alone cannot tell us the exact date. Download app. Learn About Archaeology. What is Archaeology? Common Dating Methods. Download Our App.
Chronology: Tools and Methods for Dating Historical and Ancient Deposits, Inclusions, and Remains
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.

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.

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.
Scientists first developed absolute dating techniques at the end of the 19th century. Before this, archaeologists and scientists relied on deductive dating methods, such as comparing rock strata formations in different regions. Chronometric dating has advanced since the s, allowing far more accurate dating of specimens. Adrian Grahams began writing professionally in after training as a newspaper reporter. His work has been published online and in various newspapers, including “The Cornish Times” and “The Sunday Independent.
He holds a Bachelor of Science, postgraduate diplomas in journalism and website design and is studying for an MBA. About the Author.
