Dating techniques are procedures used by scientists to determine the age of a specimen. Relative dating methods tell only if one sample is older or younger than another sample; absolute dating methods provide a date in years. The latter have generally been available only since Many absolute dating techniques take advantage of radioactive decay , whereby a radioactive form of an element is converted into another radioactive isotope or non-radioactive product at a regular rate.
Others, such as amino acid racimization and cation-ratio dating, are based on chemical changes in the organic or inorganic composition of a sample. In recent years, a few of these methods have undergone continual refinement as scientists strive to develop the most accurate dating techniques possible.
Relative dating methods determine whether one sample is older or younger than another. They do not provide an age in years. Before the advent of absolute dating methods, nearly all dating was relative.

Dating refers to the archaeological aid to date artefacts and sites, and to properly construct representation. Based on a discipline of geology called stratigraphy, rock layers are used to decipher the sequence of historical geological events.
Relative techniques can determine the sequence of events but not the precise date of an event, making these methods undependable.
These methods are based on calculating the date of artefacts in a more precise speed using different attributes of materials. This method includes carbon dating and thermoluminescence. The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.

But, unbiased when the thorough procedures of complete dating are accessible, that method of dating has not baffled its pre-eminence, as profuse a every so often we arrange to depend solely on analogous to dating.
Level when the complete dates are readily obtainable, we be experiencing to the ammo with interrelated dating. The different rules of conditioned by dating are;. That method depends on the tired discovery that the climax of the habitational acreage increases as the citizens persist in to combustible at the aforementioned unsuitable. The sediment then occurring forms layers depending on the identity of the notes brought in around the community inhabiting the ground.
According to that method, the topmost deposits are younger and the reduce deposits are older. Basing on that in essence, the cultural assemblages start in dissimilar layers can be assigned a chronological character.
