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 younger organic remains (radiocarbon dating with 14 C) to systems such as uranium–lead dating that allow determination of absolute ages for some of the oldest rocks on Earth.
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]

This makes carbon-14 an ideal dating method to date the age of bones or the remains of an organism. The carbon-14 dating limit lies around 58,000 to 62,000 years. [32] The rate of creation of carbon-14 appears to be roughly constant, as cross-checks of carbon-14 dating with other dating methods show it gives consistent results.

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.
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]
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.
