The irregular pattern of compounds is indicate this sample contains metabolites, and is from a living organism. - "AN IN-SITU RB-SR DATING & LIFE DETECTION … The isotope 86 Sr is non-radiogenic in origin and does not change, but 87 Sr is produced by the radioactive decay of 87 Rb. There is no way of anticipating what the 87 Sr is at the time of melt, but if there is 87 Rb present then it will increase with time as the rubidium isotope decays. 1979-01-01 returned sample.

A suggested method to test for this effect is argued to require rigorous statistical analysis. An associated optimal sampling technique would involve using single grain etching.

The neutron emits an electron to become a proton. For this decay reaction, λ = 1.42 x 10-11 /yr, τ 1/2 = 4.8 x 10 10 yr. at present, 27.85% of natural Rb is 87 Rb. If we use this system to plug into equation (2), then. 87 Sr* = 87 Rb (e λ t-1) (3) but, 87 Sr t = 87 Sr 0 + 87 Sr* or. 87 Sr* = 87 Sr t - 87 Sr 0 Rb-Sr dating relies on correctly measuring the Rb-Sr ratio of a mineral or whole rock sample, plus deriving an accurate 87Sr/86Sr ratio for the mineral or whole rock sample. Several preconditions must be satisfied before a Rb-Sr date can be considered as representing the time of emplacement or formation of a rock.
