Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

What are the methods of radiometric dating?

Types of radiometric datingRadiocarbon (14C) dating. Youve almost definitely heard of “carbon dating”. Potassium-argon and argon-argon dating. Uranium-lead dating. Fission-track dating. Chlorine-36 dating. Luminescence dating. Other types of radiometric dating.14 Apr 2021

What is radiometric method?

The radiometric, or gamma-ray spectrometric method is a geophysical process used to estimate concentrations of the radioelements: potassium, uranium and thorium in the near surface. This is done by measuring the gamma-rays which the radioactive isotopes of these elements emit during radioactive decay.

Where can we apply the relative dating method?

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence. The method of reading the order is called stratigraphy (layers of rock are called strata).
