Dextral or Clockwise

Fig. 4- Very often, dextral shearing stresses are represented, as dextral fault, by two opposite arrows, one above and the other below the plane, indicating that the upper part is displaced to the right.

They are dextral when the upper side of the surface is sheared to the right, that is to say, in the direction to that in which the hands of a clock rotate as viewed from in front.
