Relative dating for geological purposes
Making this processes even more difficult is the fact that due to plate tectonics some rock layers have been uplifted into mountains and eroded while others have subsided to form basins and be buried by younger sediments.With out individual time stamps the process of dating these structures could become extremely difficult. Clarke and include a large number of Lower and Middle Paleozoic species from classic localities in North America, Britain, and western and central Europe. Proceedings of the National Academy of Sciences, v. The most obvious feature of sedimentary rock is its layering.
On the other hand, basing one’s ideas on the Bible gives a very different picture.
This feature is produced by changes in deposition over time.
With this in mind geologist have long known that the deeper a sedimentary rock layer is the older it is, but how old?
