Fig. 1From: Near-seafloor magnetic mapping of off-axis lava flows near the Kairei and Yokoniwa hydrothermal vent fields in the Central Indian RidgeGeological background and seafloor bathymetry of the study area. Rock samples collected by dredge (squares) and submersible (circles) are shown as basalt (red), dolerite (brown), gabbro (yellow), and serpentinized peridotite (green). Locations of the Kairei and Yokoniwa hydrothermal fields are shown as purple starsBack to article page
