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.
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.
Our geologist would be very happy with this result.
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?
