Various dating methods
The samples were from a mile below the earth, which, according to inflated evolutionary years, were 1.5 billion years old.
The helium still locked in the samples was studied as well as the rate at which the helium diffused from the rock.
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 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.
A 10 gram sample of U-238Now that has changed, and some important discoveries are being made.
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.
• Relative dating does not tell the exact age, it can only compare items as younger and older.
• Absolute dating techniques can tell the exact age of an artifact by employing various techniques, the most popular being C-14 dating.A layer that is higher is of later age than a layer that is lower in order.
