For the winter semester 2016 we'll focus our reading and discussions on lithospheric delamination and lithospheric stability. The lithosphere is cycled back into the deeper mantle by two main processes: Subduction and delamination. Delamination refers to the process by which the lower portion of the lithosphere detaches and sinks into the asthenosphere. Delamination is thought to be an important process in the evolution and uplift of modern mountains like the central Andes or Sierra Nevada mountains in the western US, and may have also played a role in the earlier evolution of stable cratonic regions like Fennoscandia. In the course, we’ll read papers and discuss the delamination process and how it is thought to operate, the rheology of the lithosphere and its role in delamination, the predictions and evidence of lithospheric delamination in modern and ancient settings, and other important questions such as why doesn’t delamination occur in cratonic regions where the lithosphere is thick?
