Figure 4. Satellite-derived, free-air gravity map of the Kerguelen Plateau (after Sandwell and Smith, 1997). The plateau consists of five sectors: northern, central, southern, Elan B ank, and Labuan Basin (outlined in white). Current (Leg 183) and previous (Legs 119 and 120) sites are indicated by stars and circles, respectively (solid symbols = basement sites; open = sediment sites ). Squares indicate dredge and piston core sites where igneous rock (solid squares) and sediment (op en squares) were recovered.
