1pdv international dating service love sex - Radiometric dating assumptions
These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio.
This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.
Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.
This calls the whole radiometric dating scheme into serious question.
This would reduce the concentration of the potassium ions to the point that it would increase the date of the rock dramatically. Helens rock known to have come from the 1980 eruption (Creation Ex Nihilo Technical Journal) yielded erroneous dates in the millions of years.
