Types of absolute dating
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.
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.
It is clear then that absolute dating is based upon physical and chemical properties of artifacts that provide a clue regarding the true age.
This is possible because properties of rock formations are closely associated with the age of the artifacts found trapped within them.
However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.
Still, it has happened in the past that scientists have thought they'd got hold of a law of nature and then found out it was false.
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.
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.
