Table T1. Predicted depths to gabbros at 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: Depths to the axial low-velocity zone estimated from the relationship with spreading rate (following Purdy et al., 1992 and Carbotte et al., 1997a) for ocean crust spreading at 200 mm/y. Depth in mbsf includes the 250 m thick sediment cover at Site 1256.
