What is chronometric dating

This gives away the true age of the fossil that contains C-14 that starts decaying after the death of the human being or animal. Absolute Dating • Dating techniques are used in archeology to ascertain the age of old artifacts and a broad classification of these methods bifurcates them in relative dating and absolute dating • Relative dating comes to a conclusion based upon the study of layer formation of rocks.

Upper most layers are considered the youngest while the lowermost deposition is considered as oldest.

In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.

This type of dating employs many dating techniques like atomic clocks, carbon dating, annual cycle methods, and trapped electron method.

Dendrochronology is another of the popular method of finding the exact age through growth and patterns of thick and thin ring formation in fossil trees.

However, age of deposition does not mean the age of artifacts found in that layer.

Artifacts found in a layer can be compared with other items found in layers of similar age and placed in order.

The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.

The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.Seriation, on the other hand, was a stroke of genius.First used, and likely invented by archaeologist Sir William Flinders-Petrie in 1899, seriation (or sequence dating) is based on the idea that artifacts change over time.Though using similar methods, these two techniques differ in certain ways that will be discussed in this article.As the name implies, relative dating can tell which of the two artifacts is older.For example, JJA Worsaae used this law to prove the Three Age System.
