Another distinction is that a filled fracture aka
"shock vein" will be the same on each side--showing
matching halves of any feature it transects. A
slickenside will show some displacement in true fault
fashion. Features will show displacment with matrix
features offset.

 Shock vein: =\= , slickenside: _\-
