So, although the assumptions behind the calculation are mistaken and the dates are incorrect, there could also be a pattern in the results that may assist geologists understand the relationships between igneous rocks in a region. What would our geologist have thought if the date from the lab had been larger than 200 million years, say 350.5 ± 4.3 million years? Would he have concluded that the fossil date for Wapa popularity the sediments was wrong? Instead of questioning the strategy, he would say that the radiometric date was not recording the time that the rock solidified. Or he may recommend that the outcome was due to a attribute of the lava—that the dyke had inherited an outdated ‘age’. I now have a good explanation for where

The geologist may have discovered some fossils in Sedimentary Rocks A and found that they’re just like fossils present in some other rocks in the region. He assumes subsequently that Sedimentary Rocks A are the identical age as the other rocks in the area, which have already been dated by different geologists. In the same method, by identifying fossils, he may have related Sedimentary Rocks B with another rocks. For example, a geologist could look at a chopping where the rocks seem as proven in Figure 1. Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock referred to as a dyke. It is clear that the sedimentary rock was deposited and folded before the dyke was squeezed into place.
