What is chronometric dating
However, archeologists still require further information to find out the items that are oldest and those that are youngest in the order.It is left for absolute dating to come up with the precise age of an artifact.
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.
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.
This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.
It implies that relative dating cannot say conclusively about the true age of an artifact.
Dating is a technique used in archeology to ascertain the age of artifacts, fossils and other items considered to be valuable by archeologists.
There are many methods employed by these scientists, interested in the old, to get to know the age of items.
The most popular method of radio dating is radio carbon dating which is possible because of the presence of C-14, an unstable isotope of carbon.
C-14 has a half life of 5730 years which means that only half of the original amount is left in the fossil after 5730 years while half of the remaining amount is left after another 5730 years.
Seriation, on the other hand, was a stroke of genius.
