<P> Active transform faults are between two tectonic structures or faults . Fracture zones represent the previously active transform - fault lines, which have since passed the active transform zone and are being pushed toward the continents . These elevated ridges on the ocean floor can be traced for hundreds of miles and in some cases even from one continent across an ocean to the other continent . </P> <P> The most prominent examples of the mid-oceanic ridge transform zones are in the Atlantic Ocean between South America and Africa . Known as the St. Paul, Romanche, Chain, and Ascension fracture zones, these areas have deep, easily identifiable transform faults and ridges . Other locations include: the East Pacific Ridge located in the South Eastern Pacific Ocean, which meets up with San Andreas Fault to the North . </P> <P> Transform faults are not limited to oceanic crust and spreading centers; many of them are on continental margins . The best example is the San Andreas Fault on the Pacific coast of the United States . The San Andreas Fault links the East Pacific Rise off the West coast of Mexico (Gulf of California) to the Mendocino Triple Junction (Part of the Juan de Fuca plate) off the coast of the Northwestern United States, making it a ridge - to - transform - style fault . The formation of the San Andreas Fault system occurred fairly recently during the Oligocene Period between 34 million and 24 million years ago . During this period, the Farallon plate, followed by the Pacific plate, collided into the North American plate . The collision led to the subduction of the Farallon plate underneath the North American plate . Once the spreading center separating the Pacific and the Farallon plates was subducted beneath the North American plate, the San Andreas Continental Transform - Fault system was created . </P> <P> Other examples include: </P>
