Abstract
Experimental deformation of minerals and rocks provides critical data to constrain processes within the interior of the Earth. While it is not possible to give a complete description of research on mechanical properties of Earth materials in the context of this paper, we will overview those areas of research that are somewhat unique to experimental geophysics. The most notable difference is the requirement of a high-pressure environment for investigation of mechanical properties. Within this context, we will present current research pertinent to our understanding of the deformation behaviour of Earth materials: 1) our current understanding of the effects of chemical environment, especially water activity, on the mechanical properties of mantle minerals and rocks; 2) the importance of strain localisation, fabric development and deformation of Earth materials to high strains in understanding the dynamics of the lithosphère; and 3) new innovations in investigating the mechanical behaviour of the major minerals of the deep mantle, which are not stable under the conditions normally attainable in conventional deformation apparatuses.
