when did the kerguelen plateaus start to form
Kerguelen Plateau The plateau was produced by the Kerguelen hotspot, starting with or following the breakup of Gondwana about 130Â million years ago. A small portion of the plateau breaks sea level, forming the Kerguelen Islands (a French territory) plus the Heard and McDonald Islands (an Australian territory). Intermittent volcanism continues on the Heard and McDonald Islands.
