    Rubidium–strontium method The radioactive decay of rubidium87 (87 Rb) to strontium87 (87 Sr) 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 rockforming minerals in which it substitutes for the major element potassiumBecause rubidium is concentrated in crustal

    rubidium—strontium dating A radiometric dating method based on the radioactive decay of 87 Rb to 87 Sr Rubidium has two isotopes (85 Rb 7215%, 87 Rb 2785%), but only 87 Rb is radioactive 87 Rb disintegrates in a single step to 87 Sr by the emission of a lowenergy beta particle (see BETA DECAY)Unfortunately this lowenergy disintegration makes it very difficult to assess the halflife
