Transform Faults



Transform faults transform motion from one plate boundary to another.

Mid-ocean ridges are broken into numerous segments by transform faults.

The principal movement along these faults is horizontal.

Note: the apparent sense of movement on a transform fault may be different that the actual sense of movement.
Example – Figure 17.6 shows the apparent offset of the ridges is right-lateral, but because of the divergence process, the actual movement is left-lateral (as shown by the arrows). Furthermore, movement is taking place only between the two segments of the offset ridge.
