Transform faults are seismically active - but only where two different plates are adjacent to one another. Generally, oceanic transform faults occur at right angles to spreading ridges and, therefore, their orientation is indicative of the direction of plate motion. East Pacific Rise) between 10°N and 10°S, and 40°S and 55°S respectively, or manifest as shorter segments along the Atlantic Ocean spreading ridge between 0°and 40°S.
Examples can be easily seen on the Cocos-Nazca Ridge (also known as the Galapagos Spreading Centre), and the Pacific Ocean spreading ridge (i.e.
Transform plate boundary series#
Accordingly, this type of ocean transform fault forms an integral part of constructive plate boundaries, and their position is made obvious by the jagged shape of parts of the ocean-ridge system that are split into several segments by series of so-called fracture zones. Transform faults linking two constructive boundaries are the most common, and account for the displacements between adjacent segments of mid-ocean ridges. Those that link a destructive boundary with a constructive boundary. Those that link two destructive boundaries Those that link two segments of a constructive boundary Transform faults connect the end of one plate boundary to the end of another plate boundary, so there are potentially three types of transform fault: 3.8 Conservative plate boundaries and transform faultsĬonservative plate boundaries and transform faults occur when plates slide past each other in opposite directions, but without creating or destroying lithosphere.
