No matter what the radiometric date turned out to be, our geologist would always be able to ‘interpret’ it.
He would simply change his assumptions about the history of the rock to explain the result in a plausible way. Wasserburg, who received the 1986 Crafoord Prize in Geosciences, said, ‘There are no bad chronometers, only bad interpretations of them!
In other words, the age should lie between 197.2 million years and 203.6 million years.
It is clear that the sedimentary rock was deposited and folded before the dyke was squeezed into place.By looking at other outcrops in the area, our geologist is able to draw a geological map which records how the rocks are related to each other in the field.From the mapped field relationships, it is a simple matter to work out a geological cross-section and the relative timing of the geologic events.His geological cross-section may look something like Figure 2.In the same way, by identifying fossils, he may have related Sedimentary Rocks B with some other rocks.
Creationists would generally agree with the above methods and use them in their geological work.
’ In fact, there is a whole range of standard explanations that geologists use to ‘interpret’ radiometric dating results.
Someone may ask, ‘Why do geologists still use radiometric dating?
Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.
These were then eroded and Sedimentary Rocks B were deposited.
For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
