The Earth's inner core, hidden 5150 km below our feet, is primarily composed of solid iron and is exposed to pressures between 329 and 364 GPa (which are ~3.3 to 3.6 million times that of atmospheric ...

Dislocation creep is a deformation mechanism transporting shear through the crystal lattice by the motion of line defects, called dislocations. This mechanism involves the elementary processes of ...

Researchers have combined numerical modeling of dislocation glide and results from diffusion experiments to revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain ...
