Radiometric dating reliable because
In other words, the age should lie between 197.2 million years and 203.6 million years.
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.
Thus, he already ‘knows’ that the igneous dyke must be younger than 200 million years and older than 30 million years.
For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.

The field relationships are generally broad, and a wide range of ‘dates’ can be interpreted as the time when the lava solidified.
