1. rubidium-strontium dating

   Rubidium-strontium dating is a radiometric dating method used in geology and archaeology that utilizes the decay of rubidium-87 (87Rb) into strontium-87 (87Sr) to determine the age of rocks, minerals, and geological or archaeological materials. This method is based on the principle that the rubidium and strontium isotopes are present in unstable quantities within a sample, and over time rubidium gradually decays into strontium. By measuring the ratio of the two isotopes, scientists can infer the time elapsed since the formation or crystallization of the material, thus providing an estimate of its age.

1. Rubidium-strontium dating

   The rubidium-strontium dating method is a radiometric dating technique used by scientists to determine the age of rocks and minerals from the quantities they contain of specific isotopes of rubidium and strontium. Development of this process was aided by German chemist Fritz Strassmann, who later went on to discover nuclear fission with German chemist Otto Hahn and Swedish physicist Lise Meitner. The utility of the rubidium-strontium isotope system results from the fact that 87Rb decays to 87Sr with a half life of 48.8 billion years. In addition, Rb is a highly incompatible element that, during fractional crystallization of the mantle, stays in the magmatic melt rather than becoming part of mantle minerals. The radiogenic daughter, 87Sr, is produced in this decay process and was produced in rounds of stellar nucleosynthesis predating the creation of the Solar System. Different minerals in a given geologic setting can acquire distinctly different ratios of radiogenic strontium-87 to naturally occurring strontium-86 through time; and their age can be calculated by measuring the 87Sr/86Sr in a mass spectrometer, knowing the amount of 87Sr present when the rock or mineral formed, and calculating the amount of 87Rb from a measurement of the Rb present and knowledge of the 85Rb/87Rb weight ratio.8786878786
