Scientific discipline concerned with rock deformation on both small and large scales. Its scope ranges from submicroscopic lattice defects in crystals to fault structures and fold systems of the Earth's crust. Depending on the scale, the general techniques used are the same as those used in petrology, field geology, and geophysics. Furthermore, since the processes that cause rocks to deform can rarely be observed directly, computer models are also used.
