Use radiometric dating in a sentence

There are minor differences between isotopes of the same element, and in relatively rare circumstances it is possible to obtain some amount of differentiation between them. The effect is almost always a very small departure from homogeneous distribution of the isotopes -- perhaps enough to introduce an error of 0.002 half-lives in a non-isochron age. but it is rare and the effect is not large enough to account for extremely old ages on supposedly young formations.) as minerals form.

The amount of initial wouldn't change over time -- because it would have no parent atoms to produce daughter atoms.

Consider some molten rock in which isotopes and elements are distributed in a reasonably homogeneous manner.

Its composition would be represented as a single point on the isochron plot: Note that the above is somewhat simplified.

Age "uncertainty" When a "simple" dating method is performed, the result is a single number.

There is no good way to tell how close the computed result is likely to be to the actual age.

The wonderful property of isochron methods is: if one of these requirements is violated, it is nearly certain that the data will indicate the problem by failure to plot on a line.
