This is a collaborative project to investigate the                         deformation of sheet silicates, principally the common micas, by                means of triaxial deformation experiments designed to measure the               critically resolved shear stresses required for (001) dislocation               glide at temperatures to 700oC and pressures to 400 MPa, combined               with microstructural (optical and electron microscopy) and                      micorchemical (electron microprobe and IR absorption) studies to                determine the principal slip directions and their dependencies                  upon crystal chemistry and struecture.  The determination of the                stress-strain relations of micas will have direct applications to               yield envlopes constructed the continental lithosphere, to the                  mechanisms of strain localization along ductile shear zones and                 brittel faults, and to mica-bearing metamorphic tectonites.  In                 addition, this study should lead to a deeper understanding of                   dislocation glide in minearls, as it is influenced by signicicant               changes in crystal chemistry and structure within a single                      mineral group.
