SESE Surface Processes seminar Spring 2013

The Earth Surface Processes Seminar (called "Geomorphology Seminar" in the GLG courses list) runs every term, for one unit credit (repeatable any number of times, and we prefer students do enroll) on a different theme each term. The theme for this term's focus is "All Things Basin and Range". We hope that this rather broad and very cool topic, following on the heels of "Evolution of the N. American Cordillera" last semester, will attract interest.

In a typical session we discuss a single research paper or two short ones. One or a pair of students have the charge to lead the discussion each session. Guiding a discussion, pointing out interesting angles to discuss and keeping the discussion on track are the main tasks. Usually this involves leading the group through the paper, but with an aim to highlighting discussion points rather than a report/summary of all points. Sometimes digging up essential background material from previous papers is essential to either understanding of the paper, or for drawing out key discussion points. Determining whether such ancillary material is needed is up to the student leaders. As always, input for specific topics/papers folks would like to cover are greatly appreciated!

We're looking forward to a vibrant set of discussions this semester! Encouragement from Arjun and Ramón.

This week, we've selected several shorter papers in which we can address two of the key questions about structural considerations (and low vs high angle normal faulting) that have already come up during seminar this semester:
1) Is there a positive feedback of isostatic rebound from B&R extension related to different modes of normal faulting? (Spencer 1984)
2) Is the thinning of the lithosphere (as a function of time) related to different modes of normal faulting? (Buck_1993)

Also, we're attaching a third, supplemental paper that we urge you to also take a look at that addresses how rheology (thinning and heating) of the lithosphere is related to different modes of normal faulting. (Melosh 1990)
