So if these are real dates then you can hold a rock in your hand that won't form for hundreds of thousands or even millions of years yet. He then noted that the whole flow probably occured and solidified the surface at least within weeks.
As I said, carbon dating is an exception, but most other modern radiometric dates are produced using an isochron. We would be obtained with radioactive materials are the composition of basic approaches: In all cases, there is a lot of argon in the rock, indicating that the assumption is false. As a young-earth creationist, I look at this issue in a different way. Yes, there are other issues at play as is the case with any over-arching scientific idea , but to her, radiometric dating is the most important reason she believes in an old earth.

The amount of Sr that was already in the rock when it formed, for example, should be proportional to the amount of Sr that is currently there. Any isochron whatever with a positive age and a constant concentration of N can be constructed by such a mixing.
In the century since then the techniques have been greatly improved and expanded. It is not even necessary for the fractionation to treat parent and daughter equally, as long as it has the same preference for one over the other in all minerals examined; this will also preserve the isochron. Yet you state it as fact. Kennedy in Geoscience Reports, Spring , No. Suppose that A has a for the sake of argument, uniform concentration of P1 of parent, D1 of daughter, and N1 of non-radiogenic isotope of the daughter. Obviously, directly sampling mantle magma will tell us a lot, but I am not sure if it will tell us anything about radioactive dating.
