Potassium argon k ar dating
Willard Libby and his colleague Ernest Anderson showed that collected from sewage works had measurable radiocarbon activity whereas methane produced from petroleum did not.Perseverance over three years of secret research to develop the radiocarbon method came into fruition and in 1960 Libby received the Nobel Prize for chemistry for turning his vision into an invaluable tool.The Potassium-Argon dating method is the measurement of the accumulation of Argon in a mineral.
The discovery of by the French physicist, Henri Becquerel, in 1896 paved the way of measuring absolute time.Any material which is composed of carbon may be dated.Herein lies the true advantage of the radiocarbon method.When Rutherford announced his findings it soon became clear that Earth is millions of years old.These scientists and many more after them discovered that atoms of uranium, radium and several other radioactive materials are unstable and disintegrate spontaneously and consistently forming atoms of different elements and emitting radiation, a form of energy in the process.

This method dates the formation or time of crystallisation of the mineral that is being dated; it does not tell when the elements themselves were formed.
