Radio carbon dating assumptions 1on1 chat no register
These assumptions are: (1) the radioactive element decays at a constant rate (2) the rock crystal being analyzed is not contaminated by infusion of excess end product (3) the rock crystal contained no end product when it was formed (4) leaching of the parent element out of the rock sample did not occur.The Potassium-Argon dating method suffers from both leaching and contamination problems.Leaching of the parent element out of the rock would increase the age of a K-Ar sample.
Potassium, Rubidium and Uranium salts are highly soluble.As time goes on, the ratio of the parent to daughter nuclei will change and decrease (as more parent nuclei decay into daughter nuclei, the former decreases and the latter increases).Measuring this ratio gives us an idea of how long ago the rock formed. Doesn’t this assume that the rocks are closed systems?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.I have heard that this experiment has been done, demonstrating this effect (I am searching for the reference). Similar studies at the Grand Canyon found volcanic rocks dated at the top of the canyon older than those found in the bottom. One of the tests that has not been done on the method is to subject it to a double blind study.
