In order to use the valuable information provided by radiometric dating, a new method had to be created that would determine an accurate date and validate the assumptions of radiometric dating. Isotope dating satisfies this requirement, as daughter products do not decay back to the original parent element.

For this purpose, isochron dating was developed, a process "that solves both of these problems (accurate date, assumptions) at once" (Stasson 1992). 2) The process must occur at a relatively uniform rate.

While an organism is alive this exchange of Carbon continues, and the percentage of Carbon-14 in its body is the same as the percentage of Carbon-14 in the atmosphere.

By measuring the amounts of Potassium and Argon present we can date volcanic rocks that are millions of years old.However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid.These assumptions include: 1) the initial amount of the daughter isotope is known, 2) neither parent or daughter product has migrated into, or out of, the closed rock system, and 3) decay has occurred at a constant rate over time.The number used to identify the isotope refers to the total number of particles in the nucleus of each atom.Some of the different kinds of radioactive atoms used to date objects are shown in the following table: Potassium-Argon Dating Potassium atoms are used to date rocks that have formed from molten rock. Argon is an inert gasit does not chemically bond to other atoms.
