This new model for 87 Sr accumulation eliminates the need for either long-term decay of 87 Rb, or the acceleration of 87 Rb decay by many orders of magnitude. When diffusive isotope fractionation of Sr isotopes is repeated a sufficient number of times by within-mantle processes on isotopically-anomalous mantle xenoliths (each of which originally had low 88 Sr/ 86 Sr, high 84 Sr/ 86 Sr, and of the Rb/Sr line and the isochron line can be obtained by solving the equation 1-x = 0.048x, giving the result x = 0.954, which is the rubidium-87/strontium-86ratio corresponding to the given isochron line.(The corresponding strontium-87/strontium-86ratio The isotope 87 Rb decays into the ground state of 87 Sr with a half-life of 48.8 Ga and a maximum β- energy of 275 keV. λ = 1.42× /yr d = radiogenic + + Q = - 1 6. 87 Sr now = 87 Sr original + (87 Rb original - 87 Rb now) The term in parenthesis, the amount of 87 Rb that decayed into 87 Sr can be related by the radioactive decay law: 87 Rb original = 87 Rb now * (e lt) where, e is the base of the natural logarithm, Rubidium-87, Rb 87 Strontium-87, Sr 87 . Basis of the Technique. As the parent element decays, its amount decreases while the amount of the daughter element increases. This gives us a ratio of parent:daughter elements.

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.
