Zircon does incorporate initial Pb when it crystallizes. It cannot be proven that the Pb in apparently cogenetic U- or Th-free minerals is only initial Pb, and that it is identical to the initial Pb in the mineral being dated.Nor can the measured Pb isotope ratios be used to somehow decide what proportions of them are the initial Pb without recourse to unprovable assumptions about the mineral or rock’s history or their interpreted U-Th-Pb ages within an assumed deep time history.The uncertainties associated with direct half-life determinations are, in most cases, still at the 1% level, which is still significantly better than any radioisotope method for determining the ages of rock formations.However, even uncertainties of only 1% in the half-lives lead to very significant discrepancies in the derived radioisotope ages.(1969), have not been accompanied by any comparable improvement in the accuracy of the decay constants (Begemann et al.2001; Steiger and Jäger 1977), in spite of ongoing attempts (Miller 2012).

However, from a biblical perspective the earth was created by God on Day 1 of the Creation Week before the sun and the rest of the solar system were created on Day 4, all only about 6000 or so years ago.The new product line features three Capes, each mounted to their Standard, Premium, or the Sunlight-Readable 7” TFT.U-Pb radioisotope dating is now the absolute dating method of first choice among geochronologists, especially using the mineral zircon.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.All the unprovable assumptions ultimately depend on an assumed deep time history.
