摘 要:The Southwest Indian Ridge is an ultraslow spreading ridge (-14-mm/yr) that formed -150 Ma with the breakup of Gondwana. It extends 7700 km from the Bouvet to the Rodriguez Triple Junction, crossing over the flank of the large southern Geoid high centered over Marion and Crozet islands and the Conrad Rise.
