Then come the dikes/dykes and fault motion. If the fault moves in between the time each dike forms, the first dike to form would be split apart the farthest, so B had to form before the others. #SuperpositionPuzzle 7/8

There is no #SuperpositionPuzzle this week, but please enjoy this photo by the late Ron Schott who posted it in another week with no puzzle. I really appreciate that Ron shared so many wonderful pictures and supported my puzzle efforts. https://t.co/jpDIlw8VZU
