It is difficult to determine the movement direction of a transpressional zone based on internal structures. We show that the movement direction can be better defined by considering the variation in strain geometry and kinematics of differently oriented and kinematically related shear zones or different segments of a curved shear zone. Application of this method to a shear zone in the northwestern Superior Province of Manitoba shows that the movement direction there is approximately north-south, in contrast to a commonly held view for similarly oriented shear zones in the Superior Province that the movement direction is approximately east-west.
