Field Trip Numbers One and Two
Geology 364 - Stratigraphy and Basin Analysis
Dept. of Geology and Environmental Studies, James Madison University Lynn S. Fichter
It is not just enough that you know the formations we visited, you also need to be able to organize that knowledge. The questions below are strategies to help you organize and understand the geological importance of each outcrop.

Stratigraphic Column Index Map
HOW MANY, AND WHICH FORMATIONS, HAVE OR ARE EACH OF THE FOLLOWING?Red in color? Check
Quartz Arenite? Check
Bouma Sequences? Check
Hummocky sequences? Check
Point bar sequences? Check
Tidal features? Check
Anoxic (deep?) evidence? Check
And which are uniquely different for some reason? Check
OK, here is a challenge. All the formations we saw are listed below in alphabetical order. Arrange them in stratigraphic order, and tell their story.
INTERPRETATIONS OF THE FORMATIONS
And now a greater challenge. Take the list of formations in their stratigraphic order (see strat column) and reconstruct a geologic history based on the evidence in them.
Try doing this on your own, just sitting down with the formation list.
Sit down with several class mates and talk the entire history through, formations, lithofacies, color, composition, environments, tectonics, etc.
OR, try the exercise to the left, an even greater challenge.
