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.

The amount of the isotope in the object is compared to the amount of the isotope's decay products.To compensate for the loss of mass (and energy), the radioactive atom undergoes internal transformation and in most cases simply becomes an atom of a different chemical element.In terms of the numbers of atoms present, it is as if apples changed spontaneously into oranges at a fixed and known rate.Radiocarbon dating is one kind of radiometric dating, used for determining the age of organic remains that are less than 50,000 years old.For inorganic matter and for older materials, isotopes of other elements, such as potassium, uranium, and strontium, are used.
