Fig. 1

Cartoon showing formation of an oceanic core complex on a non-conservative “plutonic growth fault,” also known as an oceanic detachment fault. Red arrows show spreading asymmetry similar to that documented at Atlantis Bank due to fault capture causing the majority of newly accreted crust to spread to the left in the figure. Talc-serpentine schist (~ 1 m thick) is exaggerated for graphical purposes and is shown intruding along the active detachment fault between the upper crust and the gabbro laterally from where it crosses into mantle peridotite near the transform or a ridge discontinuity
