There are a number of useful isotope systems which constitute clocks in the rocks and are useful for geologic dating . But if asked what is the most reliable and precise method for dating the Earth and meteorites, Brent Dalyrymple would point to lead isochrons . He calls the lead method "the hourglass of the solar system" .

The lead - lead isochron method for determining the age of ancient rocks including meteorites is generally thought to be the most reliable and precise method for such dating . Dalrymple calls the lead method "the hourglass of the solar system" .

Lead isotopes are commonly used in dating rocks and provide some of the best evidence for the Earth's age . In order to be used as a natural clock to calculate the age of the earth, the processes generating lead isotopes must meet the four conditions of a natural clock: an irreversible process, a uniform rate, an initial condition, and a final condition .
Isochron dating is a common technique of radiometric dating and is applied to date certain events, such as crystallization, metamorphism, shock events, and differentiation of precursor melts, in the history of rocks . Isochron dating can be further separated into mineral isochron dating and whole rock isochron dating ; both techniques are applied frequently to date terrestrial and also extraterrestrial rocks . The advantage of isochron dating as compared to simple radiometric dating techniques is t

For this purpose, isochron dating was developed, a process "that solves both of these problems (accurate date, assumptions) at once" (Stasson 1992) . A natural clock must meet four requirements . 1) The process must be irreversible . Isotope dating satisfies this requirement, as daughter products do not decay back to the original parent element .
The stable daughter in the thorium series is lead -208 (all paths end up with lead ) . Any other isotope would work for the unstable daughter isotope in an isochron dating test . The other thing that isochron dating requires is that multiple samples be tested from the same source material .
Lead - lead dating is a method for dating geological samples, normally based on 'whole-rock' samples of material such as granite . For most dating requirements it has been superseded by uranium- lead dating (U-Pb dating ), but in certain specialized situations (such as dating meteorites and the age of the Earth ) it is more important than U-Pb dating .
The better dating method is called the isochron method of radioactive dating . This approach theoretically bypasses the issue of unknown initial conditions for isotope concentrations by combining a linear equation analysis with a nonlinear equation to simulate time evolution of isotopes in rock .
Should a point plot below the line, it could indicate that a particular sample was open to migration of the dating elements or that the sample was contaminated and lay below the isochron when the rock solidified . 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 .
Abstract . As with other isochron methods, the U-Pb isochron method has been questioned in the open literature, because often an excellent line of best fit between ratios obtained from a set of good cogenetic samples gives a resultant " isochron " and yields a derived "age" that has no distinct geological meaning .
