The Antarctic-Phoenix Ridge, also called the Phoenix Ridge, is an extinct mid-ocean ridge that consisted of three spreading ridge segments between the Antarctic Peninsula and the Scotia Sea. It initiated during the Late Cretaceous-Early Tertiary when the Phoenix Plate had divergent boundaries with the Bellingshausen and Pacific plates. Spreading along the Antarctic-Phoenix Ridge had ceased entirely by 3.3 million years ago when the small remnant of the Phoenix Plate was incorporated into the Antarctic Plate.[1]
