A free-air gravity anomaly chart has been compiled for the Amirante Arc, Amirante Basin and the western margin of the Seychelles Plateau. The new gravity data, obtained during R.R.S. ``Discovery'' cruise 101, has tracks orthogonal to the Amirante Arc at approximately 40 km separation and detailed coverage of the south and west margins of the Seychelles Plateau that has been merged with earlier data. The free-air anomaly across the southern Amirante Arc has a wavelength close to 75 km and an average amplitude of 215 mgal. Three profiles are interpreted using two-dimensional models with the Moho at 14 km depth in the Amirante and south Somali Basins and a significant variation in the depth to the mantle of between 11 and 25 km beneath the arc-trough structure. The density distributions show evidence of partial subduction analogous to that of the north Spanish margin and high lithostatic stress reflecting the absence of local isostatic compensation.
