Figure F7. Kerguelen hot spot magma output since ~130 Ma. Volumes for each of the Kerguelen Plateau-Broken Ridge LIP sectors (Coffin and Eldholm, 1994; Coffin and Gahagen, 1995) and radiometric age data (Davies et al., 1989; Whitechurch et al., 1992; Pringle et al., 1994; and Storey et al., 1996) were used to calculate the output; duration of emplacement for each domain was assumed to be equal to ±2 values for either single or multiple dates from each domain.
