Radio carbon dating false
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.
Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.
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 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.
’ 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?
