Figure F14. Proposed operations schedule in Hole 1256D during IODP Expedition 335, Superfast Spreading Rate Crust 4. Heavy red line shows our estimate of progress in Hole 1256D for Expedition 335 as scheduled for 51 days with 31.6 days of RCB coring. Transit, preparation, and wireline logging times based on previous operations in Hole 1256D. Assuming good drilling conditions, Hole 1256D should be deepened through the dike–gabbro transition zone and varitextured gabbros (coarse-grained melts of the same composition as the upper crust) and have a strong chance of penetrating down into cumulate gabbros. Upper crustal stratigraphy defined by drilling in Hole 1256D (Wilson et al., 2003, 2006; Teagle et al., 2006). Plutonic stratigraphy predicted from observations of the Oman ophiolite. Gray transparent boxes indicate uncertainty in predictions. Port = port call; Trans = transit; WL = downhole wireline experiments.
