Rheology of the lithosphere

Seminar info and schedule

For the fall semester 2016 we'll focus our reading and discussions on the rheology of the lithosphere. We'll start with a few papers about models of the rheological structure of the lithosphere, then dive into some literature about the rock mechanics experiments that provide the material property values used in rheology models. Depending on how things evolve, we also plan to start reading papers about tectonic inheritance and how past deformation may condition future deformation. Most likely this will occur later in the fall.

Seminars will take place at 12-14 in room D501 of the Exactum. You may also want to see more information about the general format of the seminar.

A tentative schedule of readings is below.
