Uranium lead dating problems funny, uranium–lead dating
These fission tracks inevitably act as conduits deep within the crystal, thereby providing a method of transport to facilitate the leaching of lead isotopes from the zircon crystal. Later, more of the crustal rock would be incorporated by melting into the magma, and thus the magma would be richer in uranium and thorium and poorer in lead. It is possible that the reason is that uranium-lead dates so rarely agree with the correct dates. These will be definite factors that will change relative concentrations of parent and daughter isotopes in some way, and call into question the reliability of radiometric dating. The many acknowledged anomalies in radiometric dating only add weight to this argument.
Uranium Lead Dating Problems
How Uranium and Thorium are preferentially incorporated in various minerals I now give evidences that uranium and thorium are incorporated into some minerals more than others. Uranium and thorium have high melting points and as magma cools, these elements crystallize out of solution and fall to the magma chamber's depths and remelt. Uranium has a much higher melting point. It turns out that uranium in magma is typically found in the form of uranium dioxide, with a melting point of degrees centrigrade. There are a number of uranium compounds with different melting points, dating a guy in an open relationship and in general it seems that the ones with the highest melting points are more stable.
First let me note that there is a lot more going on than just mixing. One would assume that initially, the concentration of N and D in different locations are proportional, since their chemical properties are very similar.
For that reason, igneous rocks of granitic composition are strongly enriched in U and Th compared to rocks of basaltic or ultramafic composition. But at the same time, it will be enriched in the elements contained in the later forming minerals, namely sodium and potassium. He then noted that the whole flow probably occured and solidified the surface at least within weeks. Often one does not get a straight line for the values.
Furthermore, here is a brief excerpt from a recent article which also indicates that isochrons often have severe problems. But then problems also arise with the new methods, and so the search goes on. In general, when an area is so complicated that I can just barely understand it, then there may be problems with the area that are more complicated still. For problems with uranium lead dating many people, radiometric dating might be the one scientific technique that most blatantly seems to challenge the bible s record of recent creation.

This calls the whole radiometric dating scheme into serious question. What radiometric dating needs to do to show its reliability is to demonstrate that no such fractionation could take place. This fact has profound implications for radiometric dating.
Later we will see that mixing of two kinds of magma, with different proportions of lead isotopes, could also lead to differences in concentrations. At any rate, there will be some effects of this nature that will produce some kinds of changes in concentration of uranium and thorium relative to lead from the top to the bottom of a magma chamber.
Such a scenario does not answer all of the questions or solve all of the problems that radiometric dating poses for those who believe the Genesis account of Creation and the Flood. The really funny thing to me is that it is very possible that we are trying to explain a phantom of our imagination. So we are investing a lot of time and energy to explain how this marvelous agreement of the various methods can arise in a creationist framework. If this is the case, they are concordant and the age determined is most probably the actual age of the specimen. So this is a valid mixing, and we are done.
