He may suggest that some other very old material had contaminated the lava as it passed through the earth.Or he may suggest that the result was due to a characteristic of the lava—that the dyke had inherited an old ‘age’. 200.4 ± 3.2 million years) implies that the calculated date of 200.4 million years is accurate to plus or minus 3.2 million years.

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.

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.

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.

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.

It relates only to the accuracy of the measuring equipment in the laboratory.
