Augite Mg# and plagioclase anorthite content plotted against sampling depth for Shinkai 6500 Dives 466-467 on the north wall of Atlantis Bank (Fig. 3). These dives represent a continuous traverse of the largest gabbro exposure at Atlantis Bank, ending at the contact with the mantle on the transform wall. This shows that the contact is not a depositional one representing the gabbro-peridotite contact, but rather an intrusive contact where evolved gabbro intruded laterally into the mantle in the transform zone
