Radiometric Dating and the Geological Time Scale
Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology. Bishop James Ussher, a 17th-century Irish cleric, for example, calculated that creation occurred in B. There were many other such estimates, but they invariably resulted in an Earth only a few thousand years old.
It is not about the theory behind radiometric dating methods, it is about their application , and it therefore assumes the reader has some familiarity with the technique already refer to "Other Sources" for more information. As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale. To get to that point, there is also a historical discussion and description of non-radiometric dating methods.

This book is a compilation of seven Creation Research Society Quarterly reprints published by the Creation Research Society , two reprints from the Proceedings of the International Conference on Creationism , and one reprint of an Institute for Creation Research Impact pamphlet., The simplest form of isotopic age computation involves substituting three measurements into an equation of four variables, and solving for the fourth.

Carbon 14 is used for this example:, which was put out by Dr. The above is offered as a simple fact of research. Knowing how faulty creationist "facts" can be, let's do a little research of our own.

Could it be that the whole scientific community has missed this point, or is it another case of creationist daydreaming? This argument was popularized by Henry Morris , p. In another creationist, Robert L.
