TīmeklisIf the initial amount of Sr is known or can be extrapolated, the age can be determined by measurement of the Rb and Sr concentrations and the 87 Sr/ 86 Sr ratio. The dates … TīmeklisThe reliability of this method was examined using the rhyolite standard JR-2, a typical sample with a high Rb/Sr ratio (Rb/Sr = 37.36). Results in the JR-2 case showed that approximately 92% of Rb and most of the matrix elements (K, Ti, Fe, Al, Mn and Na) could be removed effectively.

The rubidium-strontium dating method is a radiometric dating technique, used by scientists to determine the age of rocks and minerals from their content of specific isotopes of rubidium ( Rb) and strontium ( Sr, Sr). One of the two naturally occurring isotopes of rubidium, Rb, decays to Sr with a half-life of 49.23 billion years. The radiogenic daughter, Sr, produced in this decay process is the only one of the four naturally occurring strontium isotopes that was not produced exclusively by … TīmeklisUnlock access to over 1000 metrics with InvestingPro.
