“…Experimental studies of magnetite, which is a non-silicate with a spinel structure like chromite, have revealed that magnetite can undergo intracrystalline deformation by dislocation creep (Hennig-Michaeli and Siemes, 1982;Müller and Siemes, 1972). Recent experiments on the deformation of magnetite (Till and Moskowitz, 2013) present new flow laws and give a stress exponent value around 3, and hence we argue that the flow character is non-Newtonian, power-law creep with a stress exponent of around 3. Dislocation creep previously was not thought to be a dominant mechanism; instead, diffusional creep, which normally does not result in a strong crystallographic fabric (Wheeler, 2009) and intracrystalline deformation features, was considered the principal mechanism in the deformation of chromites (Ozawa, 1989).…”
