Scientist Realizes Important Flaw in Radioactive Dating

Depending on their oxidation state, according to Faure, uranium minerals can be very soluble in water while thorium compounds are, generally, very insoluble. This changes the chemical identity of the atom.

Either it is the result of an unknown decay process, or it is the result of fractionation which is greatly increasing the concentration of radium or greatly decreasing the concentration of uranium. Then the surrounding crystal surface would continue to grow and close up the gap, incorporating a tiny amount of magma. What has to happen next to get an isochron is that the uranium or thorium has to concentrate relative to the lead isotopes, more in some places than others. Most genetic models for uranium deposits in sandstones in the U.

This is best

These processes could influence the distribution of lead in magma chambers. It depends how fast it happened. Bowen successfully demonstrated that through fractional crystallization one magma can generate several different igneous rocks. It is also known that uranium is highly reactive.

This is actually a good argument. So there may not be anything to explain. So it is reasonable to expect that initially, the magma is rich in iron, magnesium, and calcium and poor in uranium, thorium, sodium, and potassium.

Most likely, the effect will be dependent on the age. In fact, I think this is a very telling argument against radiometric dating. Perhaps magma that is uranium rich tends to be lighter than other magma.

Researchers at asu demonstrate the false assumptions that they don't say more. This is best illustrated by the radioactive age of a sample of diamonds from Zaire.

Although these minerals crystallize in the order shown, this sequence is not a true reaction series. This can also result in isochrons being inherited in the same way.

Although these minerals crystallize

Even if one of the sources has only tiny amounts of P, D, and N, it would still produce a reasonably good isochron as indicated above, and this isochron could not be detected by the mixing test. At least, there are so many variables to consider that the relationship between radiometric ages and true ages is too complicated to disentangle at present, isochrons or no isochrons. It is very likely that some of this melt will be squeezed from the mixture into the cracks which develop in the surrounding rock.
