5 common uses of carbon dating

This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable.This radioactivity can be used for dating, since a radioactive 'parent' element decays into a stable 'daughter' element at a constant rate.

This scheme was developed in 1937 but became more useful when mass spectrometers were improved in the late 1950s and early 1960s.

This technique has become more widely used since the late 1950s.

Its great advantage is that most rocks contain potassium, usually locked up in feldspars, clays and amphiboles.

This technique is good for iron meteorites and the mineral molybdenite.

This system is highly favoured for accurate dating of igneous and metamorphic rocks, through many different techniques.
