Dhakhan Seamount, Julunggul Transform, the Minawara Seamount Chain and Karora Seamount along the Southeast Indian Ridge (SEIR).  This sonar image shows several seamounts recently formed near the spreading center where new seafloor is being created by the NE-SW divergence of the Australian and Antarctic tectonic plates.  The boundary between these plates is made up of spreading segments offset by transform faults. The westernmost seamount in the image, Dhakhan, is located due north of the intersection of the SEIR spreading center and the Julunggul transform deep.  The transform marks the offset between the two spreading segments where new seafloor is created and moves in opposite directions away from the spreading axes on either end of the transform.  The seafloor created at the western segment (and Dhakhan with it) moves northeastward at about 75 km per million years.  Directly east across the transform deep (blue), new seafloor created at the central segment moves southwestward at about the same rate.  The seafloor moving opposite directions comes into direct contact along the transform where the friction of the two plates grinding past each other causes earthquakes. The Minawara seamount chain and Karora seamount are on the Australian plate just north of the NW-SE trending spreading center.  The axis of the spreading center on the SEIR is usually shallower than the older seafloor on the flanks but due south of Australia the axis of the spreading center is marked by a valley.

The names of these seamounts are based on Australian Aboriginal mythology and are provisional pending approval.
