Uranium 235 decays to lead 207, and Thorium 232 decays to lead 208.

In addition there is another stable isotope, lead 204, that is entirely primordial and does not form via radioactive decay at all.

Furthermore, Parentium and Daughterium are so different in chemical properties that they don't otherwise occur together.

Uranium minerals themselves are too uncommon to be very useful in dating.

The most common dating method involves the use of minerals like zircon and monazite that are relatively common in granitic rocks.

You will find them, plus much more, on our website:

Several methods for dating ancient materials have been developed.

The uranium and thorium decay systems offer a multitude of radiometric dating options.

Uranium 238 decays through a series of steps to Lead 206.

This is an important topic; for evolutionists want the history of earth to span long ages, in the hope that this will make the origin and evolution of life more likely.

Therefore we shall devote an entire chapter to a discussion of every significant method, used by scientists today, to date ancient substances.

Zircon is especially useful because it frequently contains uranium in substitution for zirconium, but does not incorporate lead (as shown by the absence of Lead-204).
