The development of radiometric dating during the early decades of the 20th century, however, soon displaced all these arguments, since the latter method seemed to allow much more time for evolution.As this dating method began to be developed, a Committee on the Measurement of Geologic Time was formed by the National Research Council with Professor Alfred C.
Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.
These were then eroded and Sedimentary Rocks B were deposited.

The Committee first met in December 1923 and then began publishing in "Annual Reports," reviewing and discussing all the papers on radiometric dating during each successive year, continuing until 1955 or so.
Radiometric dating not only supports the geologic "evolution" of the Grand Canyon, it validates a central tenet in a much different theory of evolution - a theory introduced by Charles Robert Darwin in his 1859 publication, An important criticism of Darwin's theory of evolution was its requirement for "an almost infinite number of generations", when evidence at the time suggested earth was less than 100 million years old.
Nearly 50 years after Darwin published , research on radioactive elements in rocks provided the first reliable evidence that the earth was old enough to accommodate the evolution of complex organisms.The dating of rocks by the radioactive decay of certain minerals is undoubtedly the main argument today for the dogma of an old earth.But the Bible clearly teaches a recent creation of both the heavens and the earth, so Christians have often tried to reinterpret this doctrine to accommodate the long ages required by radioactive dating.by Tas Walker A geologist works out the relative age of a rock by carefully studying where the rock is found in the field.The field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them.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.
