Fake Field Trip: Fossil correlation exercise
Now that you’ve learned to recognize the various fossils in this VFE in part 1, it’s time to apply your new knowledge to a hypothetical region.
Part 2: On the basis of their fossil content, figure out the geologic ages of the strata in this cross section. The cross section shows the position and relation of the various geologic units, “A” through “H,” as well as the unconformities that separate some of them (“1” through “4”). Links appear below the cross section that will allow you to examine fossils from each geologic unit.
| Unit A fossils Unit B fossils Unit C fossils Unit D fossils Unit E fossils Unit F fossils Unit G fossils Unit H fossils |
Age of Unit A: ________________ Age of Unit B: ________________ Age of Unit C: ________________ Age of Unit D: ________________ Age of Unit E: ________________ Age of Unit F: ________________ Age of Unit G: ________________ Age of Unit H: ________________ |
How much time is missing along unconformity “1?” ________________
How much time is missing along unconformity “2?” ________________
How much time is missing along unconformity “3?” ________________
How much time is missing along unconformity “4?” ________________
