This is different to relative dating, which only puts geological events in time Most absolute dates for rocks are obtained with radiometric methods.

These use radioactive minerals in rocks as geological clocks.

Imagine we have an undiscovered element, Parentium, that has a radioactive isotope, Parentium-123, which decays to stable Daughterium-123.Absolute dating is necessary for knowing specific time e.g.by isotope K/Ar in mica, especially in the crystalline rock: igneous and metamorphic rock.If the mineral contained 1 part per million Parentium-123 and 3 parts per million Daughterium-123, we could be sure all the Daughterium-123 was originally Parentium-123.In other words there was originally 4 parts per million Parentium-123 and 0 parts per million Daughterium-123.Geologists often need to know the age of material that they find.
