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.

Creationists would generally agree with the above methods and use them in their geological work.

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 field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.

What would our geologist have thought if the date from the lab had been greater than 200 million years, say 350.5 ± 4.3 million years?

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.

(Creationists do not agree with these ages of millions of years because of the assumptions they are based on.) Because of his interest in the volcanic dyke, he collects a sample, being careful to select rock that looks fresh and unaltered.

On his return, he sends his sample to the laboratory for dating, and after a few weeks receives the lab report.

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 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.
