The Potassium-Argon dating method is the measurement of the accumulation of Argon in a mineral.
It is based on the occurrence of a small fixed amount of the radioisotope Ar with a half-life of about 1,300 million years.
If the rock containing these minerals is heated, the tracks will begin to disappear.
If the rock is heated high enough, 120C for apatite, all tracks will disappear.
The discovery of by the French physicist, Henri Becquerel, in 1896 paved the way of measuring absolute time.Here are some of the materials that can be successfully dated using this method: Potassium-Argon Dating Potassium-Argon (K-Ar) dating is the most widely applied technique of radiometric dating.Potassium is a component in many common minerals and can be used to determine the ages of igneous and metamorphic rocks.Quaternary geology provides a record of climate change and geologically recent changes in environment.U-Pb geochronology of is used for determining the age of emplacement of igneous rocks of all compositions, ranging in age from Tertiary to Early Archean.
