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.

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.By determining the number of tracks present on a polished surface of a grain and the amount of uranium present in the grain, it is possible to calculate how long it took to produce the number of tracks preserved.
