Geology a radiometric dating me od whereby e ratio of rubidium isotope to strontium in a mineral is based on e occurrence in natural rubidium of a fixed amount of e radioisotope 87 Rb which ays to e stable strontium isotope 87 Sr. RADIOMETRIC TIME SCALE Rubidium-87 Strontium-87 48.8 billion years Potassium-40 Argon-40 1.25 billion years Sa ium-147 Neodymium-143 Dating rocks by ese radioactive timekeepers is simple in eory, but e laboratory procedures are complex. e numbers of parent and dhter isotopes in each specimen are determined by various kinds. e rubidium-strontium dating me od is a radiometric dating technique used by scientists to determine e age of rocks and minerals from e quantities ey contain of specific isotopes of rubidium (87 Rb) and strontium (87 Sr, 86 Sr.. Development of is process was aided by German chemist Fritz Strassmann, who later went on to discover nuclear fission wi German chemist Otto Hahn. 31,  · For example, strontium-86 has 38 protons and 48 neutrons, whereas strontium-87 has 38 protons and 49 neutrons. Radioactive elements, such as rubidium-87 (but not strontium-86 or strontium-87. In e rubidium-strontium me od, rubidium-87 ays wi a half-life o 8.8 billion years to strontium 87. Strontium has several o er isotopes at are stable and do not ay. e ratio of strontium-87 to ano er stable isotope, say strontium-86, increases over time as more rubidium-87 turns to strontium-87. In rubidium-strontium dating, e ratio of rubidium-87 to its stable product strontium-87 gives ages to several ousand million years. In carbon dating, e proportion of carbon-14 (half-life 5730 years) to stable carbon-12 absorbed into once-living matter gives ages to several ousand years. 01, 1996 · Rubidium has a larger atomic size an strontium, so rubidium does not fit into e crystal structure of some minerals as well as o ers.
