Structure of the Kerguelen Plateau province from Seasat altimetry and seismic reflection data
Structure of the Kerguelen Plateau province from Seasat altimetry and seismic reflection data
The Kerguelen Plateau in the southern Indian Ocean stands 2?4 km above the adjacent sea floor and is 2,500 km long (Fig. 1)1,2. Seasat provided a unique data set for deriving the free-air gravity field of the region (Fig. 2)3?5. Here we report the results of a new analysis of the plateau province's structure employing both Seasat and newly-acquired multichannel seismic (MCS) data6,7 for ground truth. The northern sector is characterized by volcanism and a sedimentary basin; the southern sector by a broad anticlinal arch, major faulting, and a sedimentary basin; and the eastern sector by an abyssal basin (Labuan) and bounding ridge (William's). The three sectors argue for a more complex tectonic evolution of the feature than has been previously proposed.

Abstract
The Kerguelen Plateau in the southern Indian Ocean stands 2?4 km above the adjacent sea floor and is 2,500 km long (Fig. 1)1,2. Seasat provided a unique data set for deriving the free-air gravity field of the region (Fig. 2)3?5. Here we report the results of a new analysis of the plateau province's structure employing both Seasat and newly-acquired multichannel seismic (MCS) data6,7 for ground truth. The northern sector is characterized by volcanism and a sedimentary basin; the southern sector by a broad anticlinal arch, major faulting, and a sedimentary basin; and the eastern sector by an abyssal basin (Labuan) and bounding ridge (William's). The three sectors argue for a more complex tectonic evolution of the feature than has been previously proposed.
