Uranium-Lead dating is a radiometric dating method that uses the decay chain of uranium and lead to find the age of a rock. As uranium decays radioactively, it becomes different chemical elements until it stops at lead. The reason for stopping at lead is because lead is not radioactive and will not change into a different element. It may sound straight-forward, but there are many variables that have to be considered. The three main parameters that have to be set are the original amount of uranium and lead in the sample, the rate at which uranium and lead enter and leave the sample, and how much the rate of decay changes. Uranium-lead dating uses four different isotopes to find the age of the rock. The four isotopes are uraniumuranium, leadand lead The process of dating finds the two ratios uranium dating assumptions uranium and lead; and uranium and lead
Here I want to concentrate on another source of error, namely, processes that take place within magma chambers. To me it has been a real uranium dating assumptions opener to see all the processes that are taking place and their potential influence uranium dating assumptions radiometric dating. Radiometric dating is largely done on rock that has formed from solidified lava. Lava properly called magma before it erupts fills large underground chambers called magma chambers. Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios.
I will attempt to give you a few answers to your questions concerning radiometric dating. These books contain an exhaustive study of radiometric dates that do not fit the results evolutionists expect. There are several methods of radiometric dating. Carbon dating has limited value for evolution because its half-life is too short. The method assumes that the production of Carbon in the atmosphere from nitrogen is a process that uranium dating assumptions in equilibrium, and it is not. The other methods deal with dating igneous rocks.
Uranium dating assumptions
More about uranium dating assumptions:
The following radioactive decay processes have proven particularly useful in radioactive dating for geologic processes:. Note that uranium and uranium give rise to two of the natural radioactive seriesbut rubidium and potassium do not give rise to series. They each stop with a single daughter product which is stable. Some of the decays which are useful for dating, with their half-lives and decay uranium dating assumptions are:. The half-life is for the parent isotope and so includes both decays. Some decays with shorter half-lives are also useful. Of these, the 14 C is unique and used in carbon dating. Note that the decay constant scale in the table below was kept the same as the table above for comparison.
Most people accept the current old-earth OE age estimate of around 4. This age uranium dating assumptions obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating - A Christian Perspective. This is the crucial point: Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint. A full discussion of the topic must therefore include the current scientific challenge to the OE concept.
