Uranium–lead dating

While there are numerous natural processes that can serve as clocks, there are also many natural processes that can reset or scramble these time-dependent processes and introduce uncertainties. To try to set a reasonable bound on the age, we could presume that the Earth formed at the same time as the rest of the solar system. If the small masses that become meteorites are part of that system, then a measurement of the solidification time of those meteorites gives an estimate of the age of the Earth. The following illustration points to a scenario for developing such an age estimate. Some of the progress in finding very old samples of rock on the Earth are summarized in the following comments. It is a compound of zirconium, silicon and oxygen which in its colorless form is used to make brilliant gems.

The four isotopes are uranium , uranium, lead , and lead The process of dating finds the two ratios between uranium and lead; and uranium and lead The radiometric dater then uses the half-life of all four isotopes to find an age range the rock should be in. The half-lives of the cascade from uranium to lead has been been extrapolated to about million years and the cascade form uranium to lead has been calculated to about 4. This data is compared to a curve called the Concordia diagram.

There are a number of assumptions involved in radiometric dating with respect to long time periods. Initial quantities One key assumption is that the initial quantity of the parent element can be determined. With uranium-lead dating, for example, the process assumes the original proportion of uranium in the sample is known with reasonable accuracy.

Uranium-Lead dating

This belief in long ages for the earth and the existence of life is derived largely from radiometric dating. These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio. This age is computed under the assumption that the parent substance say, uranium gradually decays to the daughter substance say, lead , so the higher the ratio of lead to uranium, the older the rock must be. Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning. Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.
