question 1

1) What type of fold do you see?
2) What type of fault at "S"?
3) What type of fault at "Z"?
4) What feature is "F"?
5) What type of environment might have existed when layer B was deposited?

question 2
1. In the figure below, there are four stratigraphic sections (A, B, C, and D). For each section, lithologies and fossil content are presented.
Reply to the following questions:
1) Is the basal nonconformity the same age in all columns? How do you know?
2) Is the contact between the basal conglomerate-sandstone unit of the section and the overlying shale the same age everywhere? How do you know?
3) Do you think the basal conglomerate-sandstone unit in column D represents the same amount of time, less time, or more time than the same unit in column A? Why?
