Problems with carbon dating answers in genesis speak dating
As I pointed out in the article, when the isotopic abundances are being measured very near time zero and the half-life of the radioactive parent is very long, then even a small amount of radiogenic daughter being present at time zero will result in a large erroneous ‘age’ calculation.
Furthermore, a recent article “Metallic lead nanospheres discovered in ancient zircons” says (in the introductory “Significance” section): “The heterogeneous distribution of Pb can, however, affect isotopic measurement by microbeam techniques, leading to spurious age estimates.” This raises significant questions for the technique and casts doubt over its robustness.
I did not discuss this technique because it seems a pretty straightforward combination of various parent-daughter relationships.
The Wikipedia article that you reference would seem to confirm this.
To make such a claim, one would need to know independently and unarguably just what the age of the Earth actually is.
Uniformitarians assume magmas crystallized slowly over millions of years under conditions of thermodynamic equilibrium.
If there is more than one metamorphic event, and for almost every situation there would be many, the intersection of the line with the Concordia is meaningless.” I note that in the Wikipedia article that you identify, in the 0.1–1 percent range” (my emphasis) for this technique, confirming the point I made in my article that the uncertainties quoted for radiometric ages (and indeed all other quantities) are a measure of precision (or repeatability) of the .
I also note that the last sentence in the lead-in section identifies someone as “having used it [this technique] to obtain one of the earliest accurate estimates of the age of the Earth.” However, I would question how it is known that the age estimate is accurate.
He has equipment at the University of Adelaide and does the dating analysis himself.
Thus he has the knowledge of an experienced practitioner and is not just an armchair theoretician.
