Leaky transform fault
Transform fault producing new crust
A leaky transform fault is a transform fault with volcanic activity along a significant portion of its length producing new crust.[1] In addition to the regular strike-slip motion observed at transform boundaries, an oblique extensional component is present, resulting in motion of the plates that is not parallel to the plate boundary. This opens the fault, allowing melt to break through and cool on the ocean floor, producing new crust. This extensional component can come from a slight shift in the position of a plate's Euler Pole. In order to accommodate oblique motion along the plate boundary, these leaky transform faults can break up into a series of small transforms linked by short segments of spreading ridges. These new transforms will follow small circles centred on the new Euler Pole.[2]
