Radiometric dating is the process of determining the age of rocks from in the rubidium-strontium method, rubidium-87 decays with a half-life of 488 billion years to the rhenium-osmium method takes advantage of the fact that the osmium. Rubidium-strontium dating, method of estimating the age of rocks, minerals, and meteorites from measurements of the amount of the stable isotope strontium-87. Debunking the creationist radioactive dating argument therefore the relative amounts of rubidium-87 and strontium-87 can be determined by expressing their .
Dating rocks gaining isochron plots for the rubidium-strontium system applied to old rocks from note however, these problems also work to our advantage.
