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.

Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.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.’ 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?Would he have concluded that the fossil date for the sediments was wrong? Would he have thought that the radiometric dating method was flawed? Instead of questioning the method, he would say that the radiometric date was not recording the time that the rock solidified.

He may suggest that the rock contained crystals (called xenocrysts) that formed long before the rock solidified and that these crystals gave an older date.

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.

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.

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.
