The higher the uranium-to-lead ratio of a rock, the more the Pb-206/Pb-204 and Pb-207/Pb-204 values will change with time.

Those which appear the most frequently in talk.origins are reproduced below: Note that these aren't necessarily the "best" or most difficult to refute of young-Earth arguments.

However, they are quite popular in modern creation-"science" literature (even though they should not be!

And from the slope of the line we can compute the amount of time which has passed since the pool of matter became separated into individual objects.

See the Isochron Dating FAQ or Faure (1986, chapter 18) for technical detail.

The actual underlying assumption is that, if those requirements have not been met, there is no reason for the data points to fall on a line.

The resulting plot has data points for each of five meteorites that contain varying levels of uranium, a single data point for all meteorites that do not, and one (solid circle) data point for modern terrestrial sediments.Unfortunately, the age cannot be computed directly from material that is solely from the Earth.There is evidence that energy from the Earth's accumulation caused the surface to be molten.For example, Henry Morris says: He lead to similar results, i.e., a rate virtually identical to the estimated production flux.Another possible escape mechanism is direct interaction of the solar wind with the upper atmosphere during the short periods of lower magnetic-field intensity while the field is reversing.Over time, the amounts of Pb-206 and Pb-207 will change in some samples, as these isotopes are decay end-products of uranium decay (U-238 decays to Pb-206, and U-235 decays to Pb-207).
