Rubidium-strontium dating,

Rubidium-Strontium Isochrons The isotope 86 Sr is non-radiogenic in origin and does not change, The Rb-Sr isochron method is usually not applicable to recent lava flows on or near the surface because the temperatures involved are often not high enough to produce complete melts.

Isochron Dating

Rubidium–strontium method. The radioactive decay of rubidium (87 Rb) to strontium (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 e rubidium is concentrated in crustal.

Rubidium-strontium (Rb-Sr) dating was the first technique in which the whole-rock isochron method was extensively employed. Certain rocks that cooled quickly at the surface were found to give precisely defined linear isochrons, but many others did not.

Rubidium–strontium dating - Wikipedia

In addition, 86 Sr has a high neutron capture cross-section of barns for thermal neutrons and thus can produce 87 Sr independent of the presence of 87 Rb; it would not take much 87 Sr produced in this manner to seriously skew the age calculated by this method. The closed-system assumption probably does not hold for this dating method.

Rubidium-strontium Dating,

Clocks in the Rocks. The oldest ages obtained from the Rb/Sr method can be taken as one indicator of the age of the earth. The rubidium-strontium dating method is often used in geologic studies. This is a rubidium-strontium isochron for a set of samples of a Precambrian granite body exposed near Sudbury, Ontario. The data is from T. E.
