Radiometric dating method
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.
The field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.
Thus, he already ‘knows’ that the igneous dyke must be younger than 200 million years and older than 30 million years.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.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.
It relates only to the accuracy of the measuring equipment in the laboratory.
