SLIDE SET AND NOTES - GSA SHORT COURSE ON "DEFORMATION MECHANISMS AND MICROSTRUCTURES"
Jan Tullis, Christian Teyssier, and Holger Stünitz
Notes concerning experimentally deformed samples: All experimentally deformed samples illustrated have been subjected to axial compression, except where otherwise noted, and the compression direction in the slides is vertical. These samples start out as cylinders 0.25" diameter and ~0.6" long. Many slides of experimentally deformed samples show horizontal extension cracks, which result from decompression at the end of the experiments, after deformation and quenching. All samples were deformed `as-is' (with no water added or removed) unless otherwise noted. In some of the slides the colors may appear strange because most of these thin sections have been made extra thin, in order to more clearly show details of small recrystallized grains.
