Radiometric dating is also used to date archaeological materials, including ancient artifacts.Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.Any opinions in the examples do not represent the opinion of the Cambridge Dictionary editors or of Cambridge University Press or its licensors.any method of determining the age of earth materials or objects of organic origin based on measurement of either short-lived radioactive elements or the amount of a long-lived radioactive element plus its decay product The desire to push the boundaries has been a motivator in many a daring expedition, testing the human spirit and physical abilities to the utmost.

Radiometric dating is consistent with Milankovitch cycles, which depend only on astronomical factors such as precession of the earth's tilt and orbital eccentricity ( Hilgenetal. • Radiometric dating is consistent with the luminescence ...Radiocarbon dating Radiometric dating that makes use of carbon 14 is known as radiocarbon dating.
Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.
A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.
The amount of the isotope in the object is compared to the amount of the isotope's decay products.
For inorganic matter and for older materials, isotopes of other elements, such as potassium, uranium, and strontium, are used.
Mikhail Marov of the Vernadsky Institute of Geochemistry and Analytical Chemistry said scientists had determined the meteorite's age by observing the amount of radioactive isotopes and their decay byproducts, a technique called of a granodiorite at the Cuttaburra A prospect indicates that this mineralised system may be Middle Silurian in age and thus indicating that the host rocks are older than those hosting the Cobar-type deposits.
