So, although the assumptions behind the calculation are incorrect and the dates are incorrect, there could additionally be a pattern in the results that can assist geologists perceive the relationships between igneous rocks in a region. What would our geologist have thought if the date from the lab had been higher than 200 million years, say 350.5 ± 4.3 million years? Would russianbrides.com browse he have concluded that the fossil date for the sediments was wrong? Instead of questioning the method, he would say that the radiometric date was not recording the time that the rock solidified. Or he may counsel that the outcome was because of a characteristic of the lava—that the dyke had inherited an outdated ‘age’. I now have a good explanation for where

The geologist may have found some fossils in Sedimentary Rocks A and found that they are similar to fossils found in some other rocks within the region. He assumes therefore that Sedimentary Rocks A are the identical age as the other rocks within the area, which have already been dated by different geologists. In the identical means, by identifying fossils, he might have associated Sedimentary Rocks B with another rocks. For example, a geologist could look at a slicing where the rocks seem as proven in Figure 1. Here he can see that some curved sedimentary rocks have been reduce vertically by a sheet of volcanic rock called a dyke. It is clear that the sedimentary rock was deposited and folded before the dyke was squeezed into place.
