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.
Dating methods are crucial to the process of understanding the archaeological record. Dating methods encompass both Relative dating and Absolute dating methods, as well as the interpretation of archaeological context and sequence. Many disciplines of archaeological science are concerned with dating evidence.
While the results of these techniques are largely accepted within the scientific community, there are several factors which can hinder the discovery of accurate absolute dating, including sampling errors and geological disruptions. [5] This type of chronological dating utilizes absolute referent criteria, mainly the radiometric dating methods. [6]
[2] [3] [4] Two or more radiometric methods can be used in concert to achieve more robust results. [5] Most radiometric methods are suitable for geological time only, but some such as the radiocarbon method and the 40 Ar/ 39 Ar dating method can be extended into the time of early human life [6] and into recorded history.

The age of an object with reference to a fixed and specific time scale, as determined by some method of absolute dating, e.g. 10,000 BP or 1.9 mya. [1] absolute dating Ascertaining the age of an object with reference to a fixed and specific time scale (e.g. calendar years or radiocarbon years), as opposed to relative dating.

physical and chemical dating methods which provide archaeologists with absolute and relative chronologies; artifact studies; environmental approaches which provide information on past landscapes, climates, flora, and fauna; as well as the diet, nutrition, health, and pathology of people
Luminescence dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age. Instead, they are a consequence of background radiation on certain minerals. Over time, ionizing radiation is absorbed by mineral grains in sediments and archaeological materials such as quartz and potassium ...
