Creationist view of radiometric dating
His geological cross-section may look something like Figure 2.
Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.
The field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them.
For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
The basic theory of radiometric dating is briefly reviewed.
Since 1955 the estimate for the age of the Earth has been based on the assumption that certain meteorite lead isotope ratios are equivalent to the primordial lead isotope ratios on Earth.
Some evidence is also presented to show that radiometric results that are in agreement with the accepted geological time scale are selectively published in preference to those results that are not in agreement.So it was clear that the assumption of a constant, slow decay process was wrong.There must have been speeded-up decay, perhaps in a huge burst associated with Creation Week and/or a separate burst at the time of the Flood.They have their work cut out for them, however, because radiocarbon (C-14) dating is one of the most reliable of all the radiometric dating methods.This article will answer several of the most common creationist attacks on carbon-14 dating, using the question-answer format that has proved so useful to lecturers and debaters. Answer: Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen-14 (N-14) into carbon-14 (C-14 or radiocarbon).
