The final grades for our class are due December 14, December 20 at 5:00pm
I will post the grades as soon as I can, but it probably won't be much before that deadline.
- Look for graded materials outside my office around December 20 or after the holidays. Please pick them up.
- It was a pleasure to work with you all this semester! See most of you soon!
December 2, 2004
- Updated the Lectures (including putting up the Pacific-North America movies) and Labs pages.
- Updated the What-to-Know List
- PLEASE BRING IN YOUR COMPASSES AND CHECK THEM IN ON THURSDAY (DECEMBER 2). THEY COST $250 TO REPLACE.
- Information for final application exercise (December 7):
- This exercise will be the full 50 minutes of the Tuesday class!
- It will have the same format as the standard application exercise, but have one or two more questions
- Main topics will be those we have covered since the last application exercise and emphasized in lecture, however, I will expect that you know and can do facts and techniques learned earlier (such as strike and dip or stereonets or how faults work). In particular (see also What-to-Know List):
- Shear zones
- Cleavage, foliation, lineation
- Deformation Mechanisms and Microstructures
- Cordilleran tectonics with emphasis on Arizona geologic history
- Open book and open note
November 29, 2004
- Updated the Lectures page to post lecture 11
- Updated the What-to-Know List
- Updated the Labs page
- PLEASE BRING IN YOUR COMPASSES AND CHECK THEM IN WITH JOSH ON THURSDAY (DECEMBER 2). THEY COST $250 TO REPLACE.

- Topics on which you should focus for Tuesday's application exercise:
- Sandbox experiment fault system development and geometry
- Simple cross-sections
- State of stress
- Relationship between stress regime (orientation of principle stresses relative to earth surface) and fault types (normal, reverse, strike-slip)
- Webified components of the Eastern South Mountains Lab and Central South Mountains Lab
- Modified topic coverage slightly in Class schedule.
- Caught up the Lectures and Labs pages.

- Update and simplification for the last part of the homework (Geologic Cross-sections). Use the true dip as indicated for the layers in the folds (even though there would be an apparent dip in reality along the line of section). Note that the strike direction is tangential to the contacts everywhere along those folds.
- The concept of plunge is that the folds are not horizontal. If you look at pages 379-387 in D+R, you will get a feeling for this. See this graphic as well:

- I have had a lot of students talking about updating the to know list for this application exercise. Would that be possible?
--It is updated and even covers things that we have not yet. So, the simple answer is all of the Fractures and Stress What-to-Know. For the faults, I would say that just the stuff on the sandbox experiment (p. 307-309). In addition, they should know how the compass works (Appendix III-D), and how to work with planes and topography as demonstrated in the labs and in the Appendix III-G (but not the last part on intersecting planes).
- Changed the class schedule to reflect lecture and lab progress: I switched the Week 6 and 7 labs, so we will go in the field during week 7 (to the Eastern South Mountains) and do the Virtual Mapping exercises this week. I also moved the application exercises around so that they are back to being every other week.
- Caught up the Lectures and Labs pages.
