The radioactive decay of rubidium-87 (87 Rb) to strontium-87 (87 Sr) was the first widely used dating system that utilized the isochron method. Rubidium is a relatively abundant trace element in Earth’s crust and can be found in many common rock-forming minerals in which it substitutes for the major element potassium .

What does rb-sr mean? Rubidium-strontium. (noun)
The Ausralian National University, Canberra ACT This means that as partial melting occurs, Rb is going to partition to the melt in greater proportion than Sr will. From this partitioning, the mantle will become Feb 2, 2009 Unlike the K-Ar system, in the Rb-Sr and Sm-Nd systems both the initial ratio and the age are always unknown, meaning we must solve for both Rb-Sr isotopic ratios were measured on biotite and whole rocks from a suite of 21 granitoid rocks from the southern.

Online chemical separation of Rb and Sr is possible in an O 2-filled reaction cell, wherein a portion of the Sr reacts to SrO + while simultaneously no RbO + is formed. O 2 reactions provide stable analytical conditions sufficient for precise and accurate determination of Rb/Sr and Sr/Sr isotopic ratios using 80 micron laser ablation spots.
