There are those who want to use isochron calculations to discount the C14/C12 observations. ICR has three older articles that deal with the assumptions and variables of isochrons: that is the K-Ar, Rb-Sr, and the U-Pb based methods. (look online)
As well, in 2020 Vernon Cupp stated: Conclusion So, what can be said about the isochron age model? It appears more like a mixing model than a model clock. Gunter Faure points out that a study of strontium isotopes contained in alkalic rocks from the Birunga and Toro-Ankole regions of equatorial Africa produced a fictitious isochron. Y.-F. Zheng stated: It is clear that mixing of pre-existent materials will yield a linear array of isotopic ratios. We need not assume that the isotopes, assumed to be daughter isotopes, were in fact produced in the rock by radioactive decay. Thus, the assumption of immense ages has not been proven. The straight lines, which seem to make radiometric data meaningful, are easily interpreted to be the result of simple mixing. The mainstream geological community still continues to treat the results from isochron model dating as absolute scientific fact, but it’s been clearly known for 30 years there are unresolved problems with the model. The more analysis is done on the iconic isochron model, the more dubious it appears. See also subsection under Principles of God in Creation, this website for more information. |
