Upb dating

Once radioactive decay of U and Th started after creation, daughter Pb isotopes were added inside the earth.Then catastrophic plate tectonics during the Flood stirred the mantle and via partial melting added new rocks to the crust.He showed that there is still some uncertainty in what the values for these measures of the Rb decay rate differ when Rb-Sr ages are calibrated against the U-Pb ages of either the same terrestrial minerals and rocks or the same meteorites and lunar rocks.

Thus, without being able to unequivocally distinguish the daughter Pb atoms produced by in situ U and Th decay from the initial Pb atoms in a mineral or rock, it is impossible to determine their absolute U-Pb ages.

However, even uncertainties of only 1% in the half-lives lead to very significant discrepancies in the derived radioisotope ages.

The recognition of an urgent need to improve the situation is not new (for example, Min et al. It continues to be mentioned, at one time or another, by every group active in geo- or cosmochronology (Boehnke and Harrison 2014; Schmitz 2012).

There is thus no impediment to accepting and using the Bible’s account of Creation and the Flood as a reliable framework for unravelling the history of the earth and the Pb isotopes found in its minerals and rocks.

Radioisotope dating of minerals, rocks and meteorites is perhaps the most potent claimed proof for the supposed old age of the earth and the solar system.
