But the age of the rock and the proportion of argon to radio-potassium in the sample originally are not observable. In addition to the above methods of dealing with this challenge, creationists have contended a whole raft of problems with both the older and newer methods of radiometric dating. Uranium easily substitutes for zirconium while lead is strongly excluded.
