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.

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!Let us imagine that the date reported by the lab was 150.7 ± 2.8 million years.Our geologist would be very happy with this result.For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.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.

In fact, he would have been equally happy with any date a bit less than 200 million years or a bit more than 30 million years.

They would all have fitted nicely into the field relationships that he had observed and his interpretation of them.

And, of course, the reported error ignores the huge uncertainties in the Creationist physicists point to several lines of evidence that decay rates have been faster in the past, and propose a pulse of accelerated decay during Creation Week, and possibly a smaller pulse during the Flood year. He may suggest that some of the chemicals in the rock had been disturbed by groundwater or weathering.

What would our geologist think if the date from the lab were less than 30 million years, say 10.1 ± 1.8 million years? Or he may decide that the rock had been affected by a localized heating event—one strong enough to disturb the chemicals, but not strong enough to be visible in the field.

He may suggest that some other very old material had contaminated the lava as it passed through the earth.
