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.

It is best used with rocks that contain minerals that crystallised over a very short period, possibly at the same time the rock was formed.U-Pb ages of metamorphic minerals, such as zircon or monazite are used to date thermal events, including terrestrial meteoritic impacts.U-Pb ages of zircon in sediments are used to determine the provenance of the sediments. Fission-track analysis is useful in determining the thermal history of a sample or region.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.
