1) [ pedogenic ]
   Shrink-swell produced slip faces on pedo-structure faces (e.g., wedges, bowls); grooves, striations, glossy sheen. Most evident in (but not limited to) Vertisols.
   Compare: slickensides [ geogenic ].
   2) [ geogenic ]
   Vertical or oblique, roughly planar slip face produced by external forces such as tectonics (e.g., fault), or mass movement (e.g., large slump blocks; grooves, striations on slip face).
   Compare: slickensides [ pedogenic ].
