Rubidiumstrontium method the radioactive decay of rubidium87 87 rb to strontium87 87 sr was the first widely used dating system that utilized the isochron method rubidium is a relatively abundant trace element in earths crust and can be found in many common rockforming minerals in which it substitutes for the major element potassiumbecause rubidium is concentrated in crustal.

dating the isochron method many radioactive dating methods are based on minute additions of daughter products to a rock or mineral in which a considerable amount of daughtertype isotopes already exists these isotopes did not come from radioactive decay in the system but rather formed during the original creation of the elements in this case it is a big advantage to present the data in a.

How radiometric dating works in general radioactive elements decay gradually into other elements the original element is called the parent and the result of.

Rb sr dating example of research 5

radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon in which trace radioactive impurities were selectively incorporated when they were formed the method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products which form at a known constant rate of decay.

It follows that uraniumlead potassiumargon kar and rubidiumstrontium rbsr decay can be used for very long time periods whilst radiocarbon dating can only be used up to about 70000 years.

The age of the earth is 454 177 005 billion years 454 215 10 9 years 177 1 this age may represent the age of the earths accretion of core formation or of the material from which the earth formed this dating is based on evidence from radiometric agedating of meteorite material and is consistent with the radiometric ages of the oldestknown terrestrial and lunar samples.
