(c) The easternmost AAR

The easternmost segment of the AAR connects the Conrad F.Z. with the Triple Junction area. The Conrad FZ. offsets the AAR by roughly 200 km; it runs almost in E-W direction at 55S (Fig 3). Its east end intersects the AAR axis at 1:45'W forming a well developed nodal basin ($>$ 5000 m deep) and a prominent high inside corner ($\sim$ 1000 m b.s.l.). On the opposite (eastern) side of the AAR axis another broad relief occurs ($\sim$ 2000 m b.s.l.), perhaps a relict high inside corner. The N-S direction of the AAR axis at the eastern Conrad FZ. intersection changes to a SW-NE orientation to- ward the Triple Junction area. This oblique AAR segment forms a broad depression (4000 m deep, 5 km wide) that may be interpreted as a transtensional basin. The presence of strike slip tectonics may be inferred from the curved segments of seafloor relative to the MAR axis in this area.

Two dredge stations, performed on the high inside corner, recovered basalts, gabbros and peridotites,
