Figure F1. Major physiographic features and active plate boundaries of the Woodlark Basin region. The stippled area encloses oceanic crust formed during the Brunhes Chron at spreading rates labeled in millimeters per year. MT and ST = Moresby and Simbo transform faults, respectively, DE = D'Entrecasteaux Islands. Vertical bar locates Leg 180 drilling transect. Inset is the geographical location of the Woodlark Basin. Lower panels show nested meridional cross sections at 151°34.5´E: (A) regional bathymetry and (B) local structures across the incipient conjugate margins. Leg 180 drill sites are projected on the B section. Drilled basement types are labeled: D = dolerite, G = gabbro. VE = vertical exaggeration. M.S. = Moresby Seamount.
