The Kane oceanic core complex from 23oN on the Mid-Atlantic Ridge. This is one of the most spectacular core complexes we’ve discovered with the smooth detachment fault surface clearly visible. The cross section shows what the crust is likely made of: green represents mantle peridotite; blue represents frozen mantle melts forming gabbro intrusion and magenta represents the basalt lavas and sheeted dikes that normally overly the gabbros.
