In extensional terranes these occur in the regional direction of displacement and accommodate differential amounts of displacement just as tear faults. In strike-slip faulted regions, these occur at a high angle to the regional direction of displacement and connect adjacent or en echelon parallel strike-slip faults. They accommodate the transfer of displacement from one fault to the next. The term was given by Gibbs and the transfer faults actually split the extensional region into separate parts in each of which the extension rate remains uniform. In most cases these are oblique slip faults. Tear faults are commonly subsidiary to other structures such as folds, thrust faults, or normal faults. In the latter case they are commonly referred to as transfer faults.
