Question 2 (3 points): Return to the list of hypothetical geologic examples and click on "folds and an intrusion." We are again asked to determine the correct sequence of geologic events shown by the cross-section.

Along with these geologic maps, we can reconstruct a regional geologic cross-section which would be like a great "geologic slice" through the landscape.

In the next lab, we will learn how to use local geologic information from outcrops to begin to build such regional geologic maps and geologic cross-sections, but for now we just want to practice how to read them.

Remember when we drew a topographic profile for lab manual exercise #1 (page 18) on Topographic Maps?

We could draw such a profile across several miles of landscape so we would see a side-view of the land's surface over which we might be hiking.

Question 7 (8 points): Using the relative dating method you have now practiced, derive the history of the hypothetical landscape on page 173 (also shown below).

Include all the events which can be inferred from the drawing.Let's return to one of the text questions we addressed as part of last week's homework.After the practice above, try a more thorough analysis of the history of the landscape shown on page 173 of our Chernicoff/Fox textbook.Notice that the various sedimentary layers have been labeled with letters.Also an igneous intrusion is present (labeled T) and a fault is present (labeled A).You do not need to complete the second half of this particular exercise (about resolving these ambiguities in the relative dating).
