Fluorine dating: Bones from fossils absorb fluorine from the groundwater.
The amount of fluorine absorbed indicates how long the fossil has been buried in the sediments.➤ It determines the age of a rock/object using radiometric techniques.➤ Absolute dating is quantitative.➤ This technique helps determine the exact age of the remains.➤ It is more specific than relative dating.➤ Absolute dating is expensive and time-consuming.➤ It works best for igneous and metamorphic rocks.
The area of intersection of both sets depicts the functions common to both.
However, not all fossils or remains contain such elements.
Biostratigraphy: An extended version of stratigraphy where the faunal deposits are used to establish dating.
Faunal deposits include remains and fossils of dead animals.
Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations.
These remains are subjected to dating techniques in order to predict their ages and trace their history.
