From his research, our evolutionary geologist may have discovered that other geologists believe that Sedimentary Rocks A are 200 million years old and Sedimentary Rocks B are 30 million years old.

His geological cross-section may look something like Figure 2.

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!

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.

In other words, the age should lie between 197.2 million years and 203.6 million years.

However, this error is not the real error on the date.

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.
