Sintesi geologica
Uninhabited 5 x 10-km-wide Prince Edward Island lies opposite Marion Island at the N end of a submarine plateau on the Antarctic Plate immediately S of the SW Indian Ocean Ridge. It is a low-angle remnant of a large shield volcano formerly centered off the current NW shore of the island. Pleistocene and Holocene scoria cones and tuff cones are located throughout the unglaciated island, which was active contemporaneously with nearby Marion Island. Fifteen of the scoria cones and four tuff cones on the coastal plain were active during the Holocene.
