Also known as “Chronometric Dating” (2) or numerical dating (3), absolute dating study organic substances to pinpoint an actual date or define a date range.
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.
Relative dating limitations
View exact match. Display More Results. Most of these techniques produce results with a standard deviation, but they have a relationship to the calendar which relative dating techniques do not. Among the most useful chronometric dating techniques are radiocarbon dating, potassium argon dating, and thermoluminescence dating. Dendrochronology, the relationship of dated ancient trees with live trees has no standard deviation and is the most accurate of all, though not universally applicable.
INTRODUCTION. Archaeological dating has undergone rapid development as part of a The term “chronometric dating” refers to quantitative measures of time.
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. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past. All dating methods today can be grouped into one of two categories: absolute dating , and relative dating.
The former gives a numeric age for example, this artefact is years old ; the latter provides a date based on relationships to other elements for example, this geological layer formed before this other one. Both methods are vital to piecing together events of the past from the recent back to a time before humans and even before complex life and sometimes, researchers will combine both methods to come up with a date. Some of the methods covered here are tried and tested, representing early methods of examining past geological, geographical, anthropological and archaeological processes.
Most are multidisciplinary, but some are limited, due to their nature, to a single discipline. No system is completely failsafe and no method completely correct, but with the right application, they can and have aided researchers piece together the past and solve some of their discipline’s most complex problems. Any scientific discipline for which chronology is important may utilize these dating methods.
They may tell us many things including age, but also its place in a sequence of processes. Typically, this will include:. These are the scientific areas with which we most associate dating methods.

Absolute dating is the process of determining an age on a specified chronology in archaeology and geology. Some scientists prefer the terms chronometric or calendar dating , as use of the word “absolute” implies an unwarranted certainty of accuracy. In archaeology, absolute dating is usually based on the physical, chemical, and life properties of the materials of artifacts, buildings, or other items that have been modified by humans and by historical associations with materials with known dates coins and written history.
Techniques include tree rings in timbers, radiocarbon dating of wood or bones, and trapped-charge dating methods such as thermoluminescence dating of glazed ceramics. In historical geology , the primary methods of absolute dating involve using the radioactive decay of elements trapped in rocks or minerals, including isotope systems from very young radiocarbon dating with 14 C to systems such as uranium—lead dating that allow acquisition of absolute ages for some of the oldest rocks on Earth.
Radiometric dating is based on the known and constant rate of decay of radioactive isotopes into their radiogenic daughter isotopes. Particular isotopes are suitable for different applications due to the types of atoms present in the mineral or other material and its approximate age. For example, techniques based on isotopes with half lives in the thousands of years, such as carbon, cannot be used to date materials that have ages on the order of billions of years, as the detectable amounts of the radioactive atoms and their decayed daughter isotopes will be too small to measure within the uncertainty of the instruments.
One of the most widely used and well-known absolute dating techniques is carbon or radiocarbon dating, which is used to date organic remains. This is a radiometric technique since it is based on radioactive decay. Carbon moves up the food chain as animals eat plants and as predators eat other animals.

Chronometric Dating in Archaeology pp Cite as. During the latter half of this century anthropological surveys in East Africa have made significant contributions to understanding how the human species has evolved. In the past two decades, particularly, discoveries of our fossil ancestors have been made in unprecedented numbers and diversity. Detailed studies of these fossils provide new insights into human evolution, such as the origin of locomotion and cultural activity, and the evolution of the brain, among many other complex features that have come to define humanity.
Even during the time this manuscript was written, new hominid discoveries in Ethiopia and Kenya were announced that trace our earliest ancestors further back into the Pliocene. The ages assigned to these fossils have been obtained through radiometric dating of volcanic rocks interbedded with the fossiliferous sediments. Such numerical calibrations are crucial to understanding rates and timing of evolutionary change. K-Ar dating has played a key role in unraveling the temporal patterns of hominid evolution as far back as the first significant discovery of East African australopithecines at Olduvai Gorge in It was in large part due to the desire to understand the age of the Olduvai hominid remains that pioneering attempts were made to date geologically young materials using the K-Ar method.
Yet even this seminal K-Ar dating study was plagued by the seemingly insurmountable problem of contamination. The principal materials for dating East Africa hominid sites are volcanic ashes, yet many of these ashes are not deposited as primary air fall tephras Greek for ash. Rather, most are reworked by stream action and are redeposited into the sedimentary environment.
In the process of reworking, these ashes can pick up pre-existing detrital grains that, by definition, are older than the juvenile ash.
