The geologist may have found some fossils in Sedimentary Rocks A and discovered that they are similar to fossils found in some other rocks in the region.

He assumes therefore that Sedimentary Rocks A are the same age as the other rocks in the region, which have already been dated by other geologists.

(Creationists do not agree with these ages of millions of years because of the assumptions they are based on.) Because of his interest in the volcanic dyke, he collects a sample, being careful to select rock that looks fresh and unaltered.

On his return, he sends his sample to the laboratory for dating, and after a few weeks receives the lab report.

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.

He may suggest that some other very old material had contaminated the lava as it passed through the earth.

The field relationships, as they are called, are of primary importance and all radiometric dates are evaluated against them.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.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.
