Relative and absolute dating lessons

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.

Thermoluminescence: It determines the period during which certain object was last subjected to heat.

Whereas, relative dating arranges them in the geological order of their formation.

When we observe the intersection in this diagram depicting these two dating techniques, we can conclude that they both have two things in common:1.

Provide an idea of the sequence in which events have occurred.2.

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.
