is the juan de fuca plate oceanic or continental
Juan de Fuca Plate The Juan de Fuca plate system has its origins with Panthalassa's oceanic basin and crust. This oceanic crust has primarily been subducted under the North American plate, and the Eurasian Plate. Panthalassa's oceanic plate remnants are understood to be the Juan de Fuca, Gorda, Cocos and the Nazca plates, all four of which were part of the Farallon Plate.
South American Plate The South American Plate is a major tectonic plate which includes the continent of South America as well as a sizable region of the Atlantic Ocean seabed extending eastward to the African Plate, with which it forms the southern part of the Mid-Atlantic Ridge.
