Fossil dating accuracy

The field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them.For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.His geological cross-section may look something like Figure 2.Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.

It is clear that the sedimentary rock was deposited and folded before the dyke was squeezed into place.

Creationists would generally agree with the above methods and use them in their geological work.

From his research, our evolutionary geologist may have discovered that other geologists believe that Sedimentary Rocks A are 200 million years old and Sedimentary Rocks B are 30 million years old.

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.

In other words, the age should lie between 197.2 million years and 203.6 million years.
