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.
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]
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.

Often applied to the trace mineral zircon in igneous rocks, this method is one of the two most commonly used (along with argon–argon dating) for geologic dating. Monazite geochronology is another example of U–Pb dating, employed for dating metamorphism in particular. Uranium–lead dating is applied to samples older than about 1 million years.
This form of dating is the most accurate and precise absolute dating method available to archaeologists, as the last ring that grew is the first year the tree could have been incorporated into an archaeological structure. [1] Tree-ring dating is useful in that it can contribute to chronometric, environmental, and behavioral archaeological research.
Archaeological science has particular value when it can provide absolute dates for archaeological strata and artifacts. Some of the most important dating techniques include: radiocarbon dating — especially for dating organic materials; dendrochronology — for dating trees; also very important for calibrating radiocarbon dates
absolute age 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. [2]
