Clocks in the rocks radioactive dating method

Both parent and daughter isotopes are ratioed to a daughter-element isotope that is not produced by radioactive decay.

Like carbon, the shorter-lived uranium-series isotopes are constantly being replenished, in this case, by decaying uranium supplied to the Earth during its original creation.

If the flood were global in scope, radiocarbon dating is why then would we have any rocks for which a number of different methods all agree with each other?

Deposit Mineral or sandy matter settled out of water or accumulated in a vein. This is because both uranium and lead are less easily retained in many of the minerals in which they are found.

We must conclude that all evidence points towards unchanging radioactive half-lives.

The text by Dalrymple is meant to be relatively easy to read, but is also very comprehensive.

The scheme has a range of several hundred thousand years.
