This process goes on at a steady, constant rate for each isotope and scientists are able to use that rate of decay to determine how long the process has been going on how This process goes on at a steady, constant rate for each isotope and scientists are able to use that rate of decay to determine how long the process has been going on how old the rock is. Two radiometric methods used for igneous rocks are uranium-lead dating and potassium-argon dating.

Both act on the same principal of radioactive decay. The closer in agreement the measurements for these separate isotopes are, the more exact and certain the date of the rock.
