Conference paper


Gorda Ridge is a relatively short (300 km) segment of volcanic ocean ridge that extends from the Mendocino Fracture Zone (40° 20′ N) to the Blanco Fracture Zone (43° 00′ N) off the coast of Oregon and California. The whole length of the ridge is within 200 nautical miles of the United States and therefore falls within the recently proclaimed U.S. Exclusive Economic Zone. The recent discovery of hydrothermal sulfides at several locations along the ridge may provide impetus for further exploration. This chapter presents the geologic and geophysical background of Gorda Ridge and the surrounding area.
