Dating - rubidium–strontium method: the radioactive decay of rubidium-87 (87rb) to strontium-87 (87sr) was the first widely used dating system that utilized the isochron method rubidium is a relatively abundant trace element in earth’s crust and can be found in many common rock-forming minerals in which it substitutes for the major element potassium. Claim: radiometric dating is based on index fossils whose dates were assigned long before radioactivity was discovered response: this is not at all true, though it is implied by some young-earth literature radiometric dating is based on the half-lives of the radioactive isotopes these half-lives have been measured over the last 40-90 years.
