Abstract

Parent–daughter ratio: The ratio of rubidium (Rb) to strontium (Sr). The ratio is commonly expressed as 87Rb/86Sr, where the unstable Rb-87 isotope is referred to as the parent nuclide, being approximately 27 % of all rubidium. The daughter nuclide (Sr-87) is represented by Sr-86, which is stable and not subject to radiogenic ingrowth and constitutes approximately 9.9 % of all strontium.
