In the sohd massive peridotite, as shown by Van Fleets sectionsof the Castle Crags orebody,^ the displacement is relatively small, produc-ing distinct slickensides but without deformation; but where the rocks arealtered into serpentine, which is particularly fissile, slippery, and readilysusceptible to readjustment under earth stresses, the displacement maybe large and cause the fragmentation and separation of deposits intodistinct smaller bodies.
