K ar dating calculation alexandru dating scam

If all the argon was lost, this would reset the K-Ar clock to zero, and dating the rock would give us the time of metamorphism; and if we recognized the rock as metamorphic this would actually be quite useful.However, we cannot rely on all the argon being lost, and if it is not then when we apply K-Ar dating this will give us an essentially arbitrary date somewhere between the formation of the rock and the metamorphosis event.

However, the Argon, a noble gas, constitutes approximately 0.1-5% of the Earth's present day atmosphere.If we are right in thinking that there was no argon in the rock originally, then all the argon in it now must have been produced by the decay of Ar in them will be so small that it is below the ability of our instruments to measure, and a rock formed yesterday will look no different from a rock formed fifty thousand years ago.The severity of this problem decreases as the accuracy of our instruments increases.Finally, we must consider the possibility of argon loss.When a rock undergoes metamorphism, some or all of its argon can be outgassed.
