We have used electron backscatter diffraction (EBSD) to characterize the internal deformation and orientation of olivine grains within an experimentally deformed Mg2GeO4 olivine aggregate. We observe that a significant fraction of the grains contain kink bands. Our observations of kink band geometry, combined with the work of earlier authors, indicate that  slip is the dominant slip system operating in Mg2GeO4 olivine at 1000–1473 K at 0.6–1.3 GPa. Since Mg2GeO4 is a high-pressure analog for natural compositions of olivine, this is consistent with the observations made by others that the dominant slip system for olivine in the mantle switches from  to  as pressure increases. We also observed that kink bands formed in all measured olivine grains with  axes oriented within 35° of the compression direction. We thus conclude that in a randomly oriented polycrystal undergoing uniaxial deformation at low to moderate temperatures, 18% of all grains will deform by kinking and that kink band formation is an important accommodation mechanism for olivine at these conditions.
