Table T1. Predicted depths to gabbros, Site 1256.

		Depth to axial low-velocity zone			100 m of off-axis lavas			300 m of off-axis lavas
		msb	mbsf		msb	mbsf		msb	mbsf
Minimum:		725	975		825	1075		1025	1275
Maximum:		1000	1250		1100	1350		1300	1550

Notes: msb = meters subbasement. Depths to the axial low-velocity zone are estimated from the relationship with spreading rate shown in Figure F3 (following Purdy et al., 1992; Carbotte et al., 1997b) for ocean crust spreading at 200 mm/y. Depth in mbsf includes the 250 m thick sediment cover at Site 1256.
