The rubidum-strontium dating method, is one of the ways that geologists determine the age of rocks the utility of the rubidium-strontium isotope system results from the fact that different minerals in a given geologic setting can have distinctly different 87 sr/ 86 sr as a consequence of different ages, original rb/sr values and the .
