This could be needed in the Worldbuilding stack exchange instead of here, but when I was mapping out the movements of the tectonic plates, then there's a few locations where oceanic and continental plates are moving parallel to one another in opposite directions, creating transform boundaries.

I can't find anything regarding the formations that would arise from this, though I expect that something along the lines of cliffs might form, though this is pure speculation. What formations should I expect?

And as a side-note, I also found many cases of when one plate is moving parallel to the boundary, but the other plate is moving either convergent or divergent of that boundary. What formations should I expect from these as well?


The San Andreas Fault system is an excellent example of what can happen in an oceanic–continental transform fault.

It's also important to remember that plate boundaries are usually never 100% transform-like and are at an angle. This would cause either compression or extension, depending on the local geometry. A pull apart basin is an example of something like this. For instance, the dead sea is a basin on a transform fault between Israel and Jordan, and a few hundreds kilometres to the north, on the same transform, you have mountains between Lebanon and Syria.
