He would say that the date represents the time when the volcanic lava solidified.Such an interpretation fits nicely into the range of what he already believes the age to be.Let us imagine that the date reported by the lab was 150.7 ± 2.8 million years.

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.Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.These were then eroded and Sedimentary Rocks B were deposited.’ 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?

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.
