An associated optimal sampling technique would involve using single grain etching. 2020-01-17 Age of granite rocks can be determined using Rb - Sr whole rock radioactive dating method and the following age equation, (87Sr/86Sr) = (87Sr/86Sr), + (87Rb/86Sr) (ell - 1) For a suite of representative co-magmatic granitic rocks, the Rb - Sr whole rock isochron plot and relevant data are shown in the diagram. For the Rb-Sr system, λ = 1.42 x10-5. The Decay Equation Rocks that contain 87 Rb also contain initial amounts of 87 Sr, so when comparing the relative amounts of 87 Rb and 87 Sr, the amount of 87 Sr present initially must be accounted for. Also, a certain amount of 86 Sr is present that is not a product of Rb decay, this is stable. This equation has the form y = b + xm, which is that of a straight line on x–y coordinates. The slope m is equal to ( e λ t − 1), and the intercept is equal to ( D / S ) 0 .

Both gases show significantly higher reaction product formation compared to O 2 with >85% of Sr reacting with N 2 O and >70% Sr reacting with SF 6; Rb does not react with either gas.

Samarium–neodymium dating is a radiometric dating method useful for determining the ages of rocks and meteorites, based on the radioactive decay of a long-lived samarium isotope (147 Sm) to a radiogenic neodymium isotope (143 Nd). 2020-01-17 At time t = now, the ratio of both 87 Srnow and 87 Rbnow to 86 Sr can be measured; hence the equation that can be used for the dating process is . This equation has the form of a linear equation y = b + mx, where , , , and slope .

Also, a certain amount of 86 Sr is present that is not a product of Rb decay, this is stable.
