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.It relates only to the accuracy of the measuring equipment in the laboratory.Even different samples of rock collected from the same outcrop would give a larger scatter of results. He would again say that the calculated age did not represent the time when the rock solidified.’ 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?For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.

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?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.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.
