Rb sr

Rubidium metal shares similarities to potassium metal and caesium metal in physical appearance, softness and conductivity. Rubidium cannot be stored under atmospheric oxygen, as a highly exothermic reaction will ensue, sometimes even resulting in the metal catching fire.

Rb sr

The Rb-Sr method is commonly used to date Rb-rich minerals such as muscovite, biotite and K-feldspar; these minerals usually do not incorporate much Sr at the time of their formation (Goldschmidt’s rules).

Each Concentrations of Rb and Sr by X-ray fluorescence are ± 3%, whereas they are ± 1% by isotope dilution. Strontium isotope ratios were determined using a MAT 261, 90° sector mass spectrometer, using the double rhenium filament mode of ionization. Strontium isotopic compositions are normalized to 86Sr/88Sr=0.1194.
