Radiometric dating is a means of determining the "age" of a mineral specimen by determining the relative amounts present of certain radioactive elements. By "age" we mean the elapsed time from when the mineral specimen Dating formed. Radioactive elements Absolute that is, change into other elements by "half lives. The formula for the fraction remaining is one-half raised to the power given by the number of years divided by the half-life in other words raised Examples a Examples equal to the number of half-lives. If we knew the fraction of a radioactive element still remaining Dating a mineral, it would be a simple matter to calculate its age by Absolute formula.Asian Dating Service Perth
