Absolute age is the age of a geologic formation in years.

Unlike relative age, which determines whether a formation is older or younger than its surrounding formations, absolute age provides geologists with the actual age of a formation.

To find their age, two major geological dating methods are used.

These are called relative and absolute dating techniques.

This Science Struck post enlists the differences between the absolute and relative dating methods.

Geological specimens that are unearthed need to be assigned an appropriate age.

The relative dating techniques are very effective when it comes to radioactive isotope or radiocarbon dating.

However, not all fossils or remains contain such elements.

Fluorine dating: Bones from fossils absorb fluorine from the groundwater.
